Description: Proteins, in particular membrane proteins, of Hel±cobacter pylori , their preparation and use TECHNICAL FIELD OF THE INVENTION The present invention relates to novel proteins, in particular membrane proteins or proteins which are firmly associated with the membrane, which are derived from Helicobacter pylori (H. pyl ori ) and which contain one of the peptide sequences selected from SEQ ID NO: 1, 2, 3, 6, 10, 11, 12, 14, 15, 16, 17, 18 or 19 according to Tables la-lc, or to parts or homologues thereof having a minimum length of five a ino acids, and to their preparation and use as pharmaceutical compositions, in particular as vaccines, or as a diagnostic agent. Based on these data, genes coding for these and related proteins were also isolated as shown in SEQ ID NOS: 20, 21, 22, 23, 24, 25, 26 and 27. BACKGROUND OF THE INVENTION Helicobacter pylori is a Gram-negative, microaerophilic, spiral bacterium which colonizes the mucosa of the human stomach. The bacterium is the cause of chronic active gastritis and of peptic ulcer, in particular duodenal ulcer, and plays a role in the development of carcinomas of the stomach; consequently, Helicobacter pylori is an important human pathogen. Its helical shape and otility, due to from four to six flagellae, enables the bacterium to migrate through the gastric mucus in order to reach the boundary layer, which is virtually at neutral pH, between the mucus and the mucosa. Ammonium ions, which are produced during the enzymic cleavage of urea by bacterial urease, protect the pathogen from the aggressive gastric acid. The bacterium adheres to the endothelial cells of the stomach using specific adhesins. A consequence of chronic colonization of the mucosa can be an inflammatory granulocytic, and subsequently monocytic, infiltration of the epithelium which in turn, by way of inflammation mediators, contributes to the tissue destruction. Infection stimulates both a local and a systemic humoral immune response, without these responses being able to eliminate the pathogen effectively. Immunization is the conventional way of preventing infectious diseases. It is therefore important to examine this option with regard to controlling an H. pylori infection. The development of a vaccine involves identifying factors which are crucial for virulence or structures which are accessible to the human immune system for the purpose of eliminating a pathogen. It is to be assumed that antigens of this nature are present in the outer membrane of the bacterium. Thus, adhesins of 19,600 Da (P. Doig et al., 1992, J. of Bacteriology 174, 2539- 2547), 20,000 Da (D.G. Evans et al., 1993, J. of Bacteriology 175, 674-683) and 63,000 Da (C. Lingwood et al., 1993, Infection and Immunity 61, 2474-2478) are located in the outer membrane, which adhesins are candidates for an experimental vaccine which has the aim of inducing antibodies which prevent adhesion of the bacterium to the mucosal surface. In addition, the outer membrane possesses porins of 30,000 Da (M.A. Tufano et al., 1994, Infection and Immunity 62, 1392-1399), 48,000 Da, 49,000 Da, 50,000 Da, 67,000 Da (M.M. Exner et al., 1995, Infection and Immunity 63, 1567-1572) and 31,000 Da (P. Doig et al., 1995, J. of Bacteriology 177, 5447-5452) molecular weight, and also iron-regulated outer membrane proteins of 77,000 Da, 50,000 Da and 48,000 Da (D.J. Worst et al.. 1995, Infection and Immunity 63, 4161-4165) molecular weight, erythrocyte-binding antigens of 59, 000 Da and 25,000 Da (J. Huang et al . , 1992, J. of Gen. Microbiol. 138, 1503-1513) molecular weight and proteins for binding laminin, collagen I and IV, fibronectin and vitronectin (I. Kondo et al . , 1993, European J. Gastroenterol . Hepatol . 5, 63-67). In addition, proteins of 19,000 Da (E.B. Drouet et al., 1991, J. of Clinical Microbiology 29, 1620-1624), 50,000 Da (M.M. Exner et al . , 1995, Infection and Immunity 63, 1567-1572) and 30,000 Da (J. Bδlin et al . , 1995, J. of Clinical Microbiology 33, 381- 384) molecular weight, and also a 20,000 Da lipoprotein (M. Kostrzynska et al., 1994, J. of Bacteriology 176, 5938-5948) and strain-specific, surface-located antigens of 51,000 Da, 60,000 Da and 80,000 Da (P. Doig and T.J. Trust, 1994, Infection and Immunity 62, 4526-4533) have been described. The genes for the proteins of 20,000 Da (HpaA) (Evans et al.) and 20,000 Da (lpp20) (M. Kostrzynska et al.) molecular weight have now been isolated. N-terminal protein sequence data have been disclosed for the adhesins of 19,600 Da (P. Doig et al . , 1992) and 63,000 Da (C. Lingwood et al . ) molecular weight, for the porins of 48,000 Da, 49,000 Da, 50,000 Da, 67,000 Da (M.M. Exner et al.), 30,000 Da (M.A. Tufano, 1994) and 31,000 Da (P. Doig et al., 1995) molecular weight and for the 50,000 Da protein (M.M. Exner et al., 1995) .

DETAILED DESCRIPTION OF THE INVENTION AND BEST MODE The present application describes the isolation and determination of, in all, 19 proteins, in particular membrane proteins or proteins which are firmly associated with the membrane, especially integral membrane proteins, which proteins are in a molecular weight range of from 17 kD to approx. 250 kD (Tables la-lc) . The term membrane protein is generally understood to mean integral and peripheral membrane proteins and transmembrane proteins. Integral membrane proteins are proteins which are partially or entirely inserted into the cytoplasmic membrane. By contrast, peripheral membrane proteins only adhere to the surface of the membrane. Transmembrane proteins pass completely through the membrane (see, for example, B. Alberts et al. (eds). Membrane Proteins in "Molecular Biology of the Cell", 2nd ed., Garland Publishing, Inc., New York & London, 284-287, 1989). Two sequences were identified in one band in seven cases (SEQ ID NO: 2 and 3, 5 and 6, 7 and 8, 10 and 11, 13 and 14, 15 and 16, and 17 and 18), while it was only possible to identify one sequence in one band in a further five cases (SEQ ID NO: 1, 4, 9, 12 and 19) . Six N-terminal sequences from the 19 peptide sequences identified had already been described in earlier studies; these were the sequences for urease A and urease B (B.E. Dunn et al . , 1990, J. Biolog. Chem. 265, 9464-9469), for the exoenzyme S-like protein (C. Lingwood et al.), for the 50 kD membrane protein and for the porins hop B and hop C (M.M. Exner et al.). The only genes for these antigens which have so far been isolated are those for urease A and urease B (A. Labigne et al., 1991, J. Bacteriol. 173, 1920-1931). It was not possible to find the N-terminal sequences, which have already been described, of the membrane proteins of 19,600 Da (P. Doig et al., 1992), 48,000 Da, 67,000 Da (M.M. Exner et al . , 1995) and 31,000 Da (P. Doig et al., 1995) molecular weight among the 19 sequences which are described in accordance with the invention. Thus, the protein which is described by SEQ ID NO: 14 cannot be attributed, either, to the protein having the molecular weight of 31,000 Da (P. Doig et al., 1995). The remaining 13 amino terminal protein sequences of the 19 amino terminal protein sequences according to Tables la-lc have not been described. It is to be assumed that these sequences can be attributed to Helicobacter pyl ori proteins which have not previously been identified. It was surprising, therefore, that it was possible to demonstrate a large number of additional, novel H. pylori proteins in a Sarkosyl ® -insoluble fraction. The proteins are very probably integral proteins of the outer membrane or proteins which are firmly associated with the membrane. They are therefore particularly suitable for use as candidates for developing a vaccine or a diagnostic agent. The invention describes proteins, in particular membrane proteins or proteins which are firmly associated with the membrane, especially integral membrane proteins, in particular Sarkosyl ® -insoluble integral membrane proteins of H. pylori , which contain one of the peptide sequences selected from SEQ ID NO: 1, 2, 3, 6, 10, 11, 12, 14, 15, 17, 18 or 19 according to Tables la-lc, or to parts or homologues thereof having a minimum length of five, preferably six amino acids, with these peptide sequences preferably constituting N-terminal sequences of the said proteins. The novel peptides are particularly preferred which exhibit at least ten consecutive amino acids selected from the sequences having the SEQ ID NO: 1, 2, 3, 6, 10, 11, 12, 14, 15, 16 and 19. In addition. those said parts are in particular preferred which contain an uninterrupted sequence of unambiguously specified amino acids. The term "part" in the context of "part(s) of a sequence" in the present invention is defined herein as meaning a sequence of amino acids which can form a T-cell or B-cell epitope. Such an amino acid sequence is usually of a minimum of approximately four to eight amino acids. The term "homologue (s) " in the context of the present invention is defined herein as meaning the same protein or peptide of a different strain of H. pylori but exhibiting the same function. Thus, although the actual amino acid sequences may not be identical between homologous proteins or peptides from different strains of H. pylori , the differences between the amino acid sequences merely represent strain-specific differences; the function of the homologues is identical. In a particular embodiment, the protein containing a peptide sequence having the SEQ ID NO: 1 according to Table la has a molecular weight of approx. 250 kD, the protein containing a peptide sequence having the SEQ ID NO: 2 according to Table la has a molecular weight of approx. 110 kD, the protein containing a peptide sequence having the SEQ ID NO: 3 according to Table la has a molecular weight of approx. 100 kD, the protein containing a peptide sequence having the SEQ ID NO: 6 according to Table la has a molecular weight of approx. 60 kD, the protein containing a peptide sequence having the SEQ ID NO: 10 according to Table lb has a molecular weight of approx. 42 kD, the protein containing a peptide sequence having the SEQ ID NO: 11 according to Table lb has a molecular weight of approx. 42 kD, the protein containing a peptide sequence having the SEQ ID NO: 12 according to Table lb has a molecular weight of from approx. 32 to approx. 36 kD, the protein containing a peptide sequence having the SEQ ID NO: 14 according to Table lc has a molecular weight of approx. 30 kD, the protein containing a peptide sequence having the SEQ ID NO: 15 according to Table lc has a molecular weight of approx. 28 kD, the protein containing a peptide sequence having the SEQ ID NO: 16 according to Table lc has a molecular weight of approx. 28 kD, the protein containing a peptide sequence having the SEQ ID NO: 17 according to Table lc has a molecular weight of approx. 25 kD, the protein containing a peptide sequence having the SEQ ID NO: 18 according to Table lc has a molecular weight of approx. 25 kD, and the protein containing a peptide sequence having the SEQ ID NO: 19 according to Table lc has a molecular weight of approx. 17 kD. The generally available H. pylori strain No. ATCC 43504 is used, for example, as the starting material when isolating the proteins, with it being possible, in particular, to carry out the following procedural steps: (a) isolating the proteins by means of differential solubilization, in particular using Sarkosyl ® (an N- lauroylsarcosine) in accordance with the method of Blaser et al. (1983, Infect. Immun. 42, 276-284), (b) separating the proteins, which have been isolated in accordance with step (a) , by means of gel electrophoretic methods, preferably by means of SDS polyacrylamide gel electrophoresis, with use being made, in particular, of polyacrylamide gels having differing polyacrylamide contents, in particular containing approx. 8, 10 or 16% polyacrylamide, and (c) isolating the proteins, which have been separated in accordance with step (b) , by means of known methods, for example by elution or by isolation on a membrane . For the purpose of isolating and characterizing the proteins according to the present invention, the proteins were first of all obtained using the method of Blaser et al. (see above). The bacteria, which had been disrupted in a glass bead homogenizer, were freed of intact bacteria by centrifugation at 5000 g; the supernatant was then centrifuged at 100,000 g. The pellet was dissolved in Sarkosyl ® , and the Sarkosyl ® -insoluble fraction, which contains the integral membrane proteins in particular, was centrifuged off. The pellet was resuspended in distilled water and fractionated by SDS polyacrylamide gel electrophoresis- (PAGE) . In this connection, it was found that SDS-PAGE, in contrast to HPLC, was a very effective method for separating Sarkosyl ® -insoluble proteins. For this, the gels were pretreated with methionine in order to prevent oxidation of the methionine residues. After the run, the proteins were transferred from the SDS gel to a PVDF membrane (Immobilon P ® , from Millipore) , with 0.005% SDS being added to the cathode buffer in order to complete the transfer of the very insoluble proteins. For sequence analysis, the protein bands from four tracks, in each case, were cut out of the PVDF membrane and Ed an amino acid degradation was carried out in a 477A fluid-phase sequencer (Applied Biosystems, Inc. (ABI) ) to determine the amino acid sequence. While it is possible further to fractionate the proteins which run in one band, for example by means of isoelectric focusing or two- dimensional gel electrophoresis, this is not necessary for an unambiguous sequence analysis since the sequences can be assigned unambiguously on the basis of the different protein contents of the proteins which run in one band. The amino acids which are labelled Xaa in the sequence listing can be explained as follows: The non-identifiable amino acids can be caused by interference due to impurities in the first sequencing step, a non-analysable amino acid, such as Cys or Trp, a modifiable amino acid which is missing in the elution programme, or an amino acid, such as Ser or Thr, which is difficult to determine, basically due to low sequence yields. Different bands can also contain two proteins of very similar molecular weights in different quantities. This then results in two sequences which then also have to be assigned unambiguously on account of the different frequency of the individual amino acids. The present invention also describes the peptides which are designated by the sequences according to SEQ ID NO: 1, 2, 3, 6, 10, 11, 12, 14, 16, 17, 18 or 19 according to Tables la-lc, or to parts or homologues thereof having a minimum length of five amino acids, in particular of six amino acids, which can be prepared, for example, by well-known chemical peptide synthesis (Barani, G. & Merrifield, R. B. in "The Peptides: Analysis, Synthesis and Biology" (Gross E., ed.). Vol. 2, Academic Press, 1980, Johannes Meyenhofer Verlag; Bodanszky, M. & Bodanszky, A. "The practice of peptide synthesis". Springer Verlag, 1984) . The novel peptides are particularly preferred which possess at least ten consecutive amino acids selected from the sequences having the SEQ ID NO: 1 , 2 , 3, 6, 10, 11, 12, 14, 15, 16 and 19. Furthermore, those said peptides are, in particular, preferred which contain an uninterrupted sequence of unambiguously determined amino acids, as is the case with the sequences from SEQ ID NO: 12, 14 and 15. The present application also describes antibodies which can also be prepared by methods which are well known to the skilled person (see, for example, B.A. Diamond et al. (1981), The New England Journal of Medicine, 1344-1349) and which are directed against one or more of the novel proteins or peptides. The skilled person is also familiar, from J. Sambrook et al. (1989, "Molecular Cloning, A Laboratory Manual", 2nd edn.. Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y.), with methods for preparing polynucleotides which encode the novel proteins or peptides. In particular, the skilled person knows, on the basis of the genetic code, the nucleotide sequences which encode the peptides according to the sequence listing. In particular, the nucleotide sequences are preferred which occur most frequently in accordance with the rules for the frequency of use of the different codons in Helicobacter pylori . These nucleotide sequences can be prepared, for example, by means of chemical polynucleotide synthesis (see, for example, E. Uhlmann & A. Peyman (1990), Chemical Reviews, 543-584, Vol. 90, No. 4) . For example, oligodeoxynucleotides which have been prepared in accordance with these rules can be employed for screening Helicobacter pylori gene libraries using known methods (J. Sambrook et al., 1989, "Molecular Cloning, A Laboratory Manual", 2nd edn., Cold Spring Harbor Laboratory, Cold Spring Harbor, NY) . Furthermore, taking the sequence data as a basis, peptides can be synthesized which are employed for obtaining antisera. Gene expression libraries can then be screened using these antisera. The clones resulting from these different screening methods can then be employed, by isolating and sequencing the inserted DNA fragments, for identifying DNA sequence segments which encode the N-terminally sequenced protein segments of the proteins. If the inserted DNA fragments do not contain the complete gene encoding any particular protein, these DNA fragments can be used to isolate the complete genes by screening other gene libraries. The genes which have been completely isolated in this manner can then be expressed, in accordance with the state of the art, in various well- known systems in order to obtain the corresponding protein. Using oligonucleotides deduced from the N- terminal sequences of SEQ ID NOS: 5, 7, 8, 10, 12 and 15, the genes corresponding to the SEQ ID NOS: 5, 8, 10, 12 and 15 were isolated and are specified as SEQ ID NOS: 20 (catalase) , 24 (50 kD membrane protein), 25 (42 kD protein), 26 (36/35/32 kD protein) and 23 (28 kD protein) . The gene coding for Hop C could not be isolated using oligonucleotide 7. However, oligonucleotide 7 hybridizes with an homologous gene specified as SEQ ID NO: 21 (Hop X) . Two additional genes which belong to this family were able to be isolated and are specified as SEQ ID NO: 21 (Hop Y) and SEQ ID NO: 22 (Hop Z) . Another approach is given by the recent access to the complete geno ic sequence of H. pylori on the internet which allowed, for example, the identification Of SEQ ID NO: 27. The novel proteins, peptides, antibodies and polynucleotides, and their expression products, can now be used, in accordance with methods known to the skilled person, for preparing a pharmaceutical composition , in particular a vaccine, or a diagnostic agent. Those regions of the proteins which, on the one hand, occur, if possible, in all H. pylori strains, and, on the other hand, bring about the formation of protective antibodies, are particularly suitable for preparing vaccines. A special preference is given to the regions which project from the surface of the bacteria. Such vaccines may either be prophylactic (to prevent infection) or therapeutic (to treat disease after infection) . These vaccines comprise antigen or antigens, usually in combination with "pharmaceutically acceptable carriers," which include any carrier that does not itself induce the production of antibodies harmful to the individual receiving the composition. Suitable carriers are typically large, slowly metabolized macromolecules such as proteins, polysaccharides, polylactic acids, polyglycolic acids, polymeric amino acids, amino acid copolymers, lipid aggregates (such as oil droplets or liposomes), and inactive virus particles. Such carriers are well known to those of ordinary skill in the art. Additionally, these carriers may function as immunostimulating agents ("adjuvants") . Furthermore, the antigen may be conjugated to a bacterial toxoid, such as a toxoid from diphtheria, tetanus, cholera, H. pylori, etc. pathogens. Preferred adjuvants to enhance effectiveness of the composition include, but are not limited to: (1) aluminum salts (alum) , such as aluminum hydroxide, aluminum phosphate, aluminum sulfate, etc; (2) oil-in-water emulsion formulations (with or without other specific immunostimulating agents such as muramyl peptides (see below) or bacterial cell wall components) , such as for example (a) those formulations described in PCT Publ. No. WO 90/14837, including but not limited to MF59 (containing 5% Squalene, 0.5% Tween 80, and 0.5% Span 85 (optionally containing various amounts of MTP-PE (see below), although not required) formulated into submicron particles using a microfluidizer such as Model HOY microfluidizer (Microfluidics, Newton, MA) ) , (b) SAF, containing 10% Squalane, 0.4% Tween 80, 5% pluronic-blocked polymer L121, and thr-MDP (see below) either microfluidized into a submicron emulsion or vortexed to generate a larger particle size emulsion, and (c) RibiTM adjuvant system (RAS) , (Ribi Immunochem, Hamilton, MT) containing 2% Squalene, 0.2% Tween 80, and one or more bacterial cell wall components from the group consisting of monophosphorylipid A (MPL) , trehalose dimycolate (TDM), and cell wall skeleton (CWS) , preferably MPL + CWS (DetoxTM) ; (3) saponin adjuvants, such as StimulonTM (Cambridge Bioscience, Worcester, MA) may be used or particles generated therefrom such as ISCOMs (immunostimulating complexes); (4) Complete Freunds Adjuvant (CFA) and Incomplete Freunds Adjuvant (IFA); (5) cytokines, such as interleukins (e.g., IL-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-12, etc.), interferons (e.g., gamma interferon) , macrophage colony stimulating factor (M-CSF) , tumour necrosis factor (TNF) , etc; and (6) other substances that act as immunostimulating agents to enhance the effectiveness of the composition. Alum and MF59 are preferred. As mentioned above, muramyl peptides include, but a r e n o t l i m i t e d t o , N-acetyl-muramyl-L-threonyl-D-isoglutamine (thr-MDP) , N-acetyl-normuramyl-1-alanyl-d-isoglutamine (nor-MDP) , N-acetylmuramyl-l-alanyl-d-isoglutaminyl-l-alanine-2- (1 ' -2 * -dipalmitoyl-sn-glycero-3-huydroxyphosphoryloxy) - ethyla ine (MTP-PE), etc. The immunogenic compositions (e.g., the antigen, pharmaceutically acceptable carrier, and adjuvant) typically will contain diluents, such as water, saline, glycerol, ethanol, etc. Additionally, auxiliary substances, such as wetting or emulsifying agents, pH buffering substances, and the like, may be present in such vehicles. Typically, the immunogenic compositions are prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection may also be prepared. The preparation also may be emulsified or encapsulated in liposomes for enhanced adjuvant effect, as discussed above under pharmaceutically acceptable carriers. Immunogenic compositions used as vaccines comprise an immunologically effective amount of the antigenic polypeptides, as well as any other of the above-mentioned components, as needed. By "immunologically effective amount", it is meant that the administration of that amount to an individual, either in a single dose or as part of a series, is effective for treatment or prevention. This amount varies depending upon the health and physical condition of the individual to be treated, the taxonomic group of individual to be treated (e.g., nonhuman primate, primate, etc.), the capacity of the individual's immune system to synthesize antibodies, the degree of protection desired, the formulation of the vaccine, the treating doctor's assessment of the medical situation, and other relevant factors. It is expected that the amount will fall in a relatively broad range that can be determined through routine trials. The immunogenic compositions are conventionally administered parenterally, e.g., by injection, either subcutaneously or intramuscularly. Additional formulations suitable for other modes of administration include oral and pulmonary formulations, suppositories, and transdermal applications. Dosage treatment may be a single dose schedule or a multiple dose schedule. The vaccine may be administered in conjunction with other immunoregulatory agents . The present invention describes, therefore, pharmaceutical compositions, in particular vaccines, and diagnostic agents which comprise one or more of the novel proteins and/or one or more of the novel peptides or one or more of the novel antibodies or one or more of the novel polynucleotides or one or more expression products of the novel polynucleotides. For example, according to the present invention, a DNA vaccine can be prepared on the basis of the polynucleotides, or a diagnostic agent can be prepared on the basis of the polymerase chain reaction (PCR diagnosis), or an immunotest, for example a Western blot test or an enzyme immunotest (ELISA) can be prepared on the basis of the antibodies. Furthermore, the novel proteins or peptides, or their immunogenic moieties, in particular when they contain an uninterrupted sequence of unambiguously determined amino acids, having a minimum length of five amino acids, preferably six amino acids and, in particular, in the case of the novel peptides having the SEQ ID NOS: 1, 2, 3, 6, 10, 11, 12, 14, 15, 16 and 19 and peptides or proteins encoded by the DNA sequences of SEQ ID NOS: 20, 21, 22, 23, 24, 25, 26 and 27, at least ten consecutive amino acids, can be used as antigens for immunizing mammals. In this context, the two C-terminal regions Cl and C2 specific for H. pylori catalase (c.f. Example 6) can also be used as immunogens . The antibodies which are formed by the immunization, or antibodies which are prepared by means of recombinant DNA methods (see, for example, Winter G. & Milstein C. (1991) Nature, 293-299, Vol. 349), can, inter alia, prevent adhesion of the bacteria to the mucosal surface, attract macrophages for the purpose of eliminating bacteria, and activate the complement system for the purpose of lysing the bacteria. The following examples are intended to clarify the invention. EXAMPLES Example 1: Culture of Helicobacter pylori The H. pylori stain ATCC 43504 was passaged under microaerophilic conditions (BBL Jar/Campy Pak Plus, from Becton & Dickinson) on Columbia Agar plates containing 5% horse blood (incubation 48 h, 37°C) . Three plates were rinsed off when inoculating a 500 ml flow-spoiler flask (100 ml of Columbia broth, 7% FCS) ; during the incubation (BBL Jar/Campy Pak Plus; 48 h, 37°C, 90 rpm) , the OD 590 rose from 0.3 to 2.0. The bacteria were harvested by centrifugation at 10,000 rpm and washed twice with physiological sodium chloride solution. E am le 2 : Isolation of Helicobacter pylori outer meinbrane proteins The preparation of the outer membrane protein fraction, with the inner and outer membrane proteins being separated by means of differential solubilization with Sarkosyl ® (Ciba-Geigy AG) , was carried out using the method of Blaser et al. In this method, the bacterial cultures are harvested in the phase of late logarithmic growth, washed in 10 mM Tris buffer (pH 7.4) and disrupted with glass beads in a ho ogenizer (Institut fiir Molekularbiologie und Analytik (IMA), Germany) at 4°C and 4000 rpm for 15 min. After that, the glass beads are removed by filtration and the bacterial suspension is centrifuged at 5000 g for 20 min in order to remove intact cells. The cell walls are pelleted out of the supernatant by centrifuging at 100,000 g for 60 minutes and at 4°C. The resulting pellet is resuspended with a 1% solution of Sarkosyl ® in 7 mM EDTA, and the suspension is incubated at 37°C for 20 min. The Sarkosyl ® -insoluble fraction, which contains the integral membrane proteins, is pelleted by centrifugation at 50,000 g for 60 minutes and at 4°C and the pellet is resuspended in sterile distilled water; the suspension is then stored at -20°C. Example 3: SDS polyacrylamide gel electrophoresis and blotting Gel preparation, and the electrophoresis, were carried out in a BioRad (Munich) Protean II xi slab cell apparatus. The chemicals employed, and the polyacrylamide monomer (as a 30% solution containing 0.8% bisacryla ide) , were obtained from Oxford GlycoSystems (Oxford, UK) . In addition to a 10% standard gel, gels containing polyacrylamide contents of 8% and 16% were also especially employed for carrying out separations in the high-molecular weight and low-molecular weight ranges, respectively. The thickness of the gel was 1 mm. In order to eliminate undesirable oxidizing properties of the ammonium persulphate used for preparing the gel, all the wells of the gel were filled with a solution containing 50 pM of L-methionine/microlitre and left to stand overnight. After the solution has been sucked off on the following day, and after each of the wells has once again been filled with 10 microlitres of this solution in each case, a preliminary electrophoresis takes place. This preliminary treatment prevents the methionine residues of the protein from being oxidized and thereby enables a protein cleavage with BrCN (Met cleavage site) to be carried out if required. The membrane protein fraction starting material is dissolved in 1.5% SDS, 2.5% mercaptoethanol, 5% glycerol and bromophenol blue in 63 mmol/1 Tris buffer, pH 6.8, and fractionated by SDS polyacrylamide gel electrophoresis. Protein transfer from the SDS gel to the PVDF membrane (Immobilon P ® , from Millipore) is carried out in a BioRad (Munich) Trans Blot SD apparatus, under modified conditions. For the purposes of completing the protein transfer, 0.005% SDS is added to the cathode buffer, thereby counteracting too rapid an impoverishment of SDS in the gel. The use of six filter papers, which are soaked with this buffer, on the cathode side is found to give optimum results in this connection. The blot was then stained with amidoblack using the protocol of R. Westermeier (Elektrophorese Praktikum (Electrophoresis Laboratory Manual) VCH Verlag Weinheim, 1990, ISBN 3-527-28172-X) . Example 4 : N-terminal Edman degradation The Edman amino acid degradation, and the determination of the PTH amino acids, were carried out in a 477 A liquid phase sequencer having an on-line 120A HPLC analyser (ABI) . For the analyses, the corresponding bands from, in each case, four tracks were cut out of the PVDF blot membrane and sequenced after a washing step, as recommended by ABI. The number of sequencing steps was 5 to 25 (depending on the quantity of substance available for sequencing) . The Cys and Trp PTH amino acids cannot be detected under the conditions which were chosen. Example 5 : Deduction of oligonucleotides for screening gene libraries and for identifying DNA fragments via Southern Blot analysis The following oligonucleotides were deduced from the resulting N-terminal sequences of SEQ ID NOS: 5, 7, 8, 10, 12 and 15: The oligonucleotides were deduced using the species-specific codon usage of Helicobacter pylori , which had been determined from 19 known H. pylori genes, and using the base inosine (I), which is capable of undergoing stable base pairing with the bases adenine (A) , cytosine (C) and thymine (T) with, in each case, two hydrogen bridges. When carrying out the deduction, the degeneracy of the codon was kept as low as possible. Example 6: Isolation and characterization of the genes using the oligonucleotides deduced from the peptide sequences of SEQ ID NOS: 5, 7, 8, 10, 12 and 15 The oligonucleotides which had been deduced from the peptide sequences of SEQ ID NOS: 5, 7, 8, 10, 12 and 15 were labelled with digoxigenin (DIG) using a kit manufactured by Boehringer Mannheim (DIG Oligonucleotide 3'-End Labelling Kit) and employed for screening a H. pylori gene library which had been prepared using a kit manufactured by Stratagene (Predigested ZAP Express™ BamHI/CIAP Vector Cloning Kit) at 32°C under standard conditions. Using oligonucleotides 1, 3 and 6, it was possible to identify clones which carry DNA fragments containing sequences which encode the peptide sequences of SEQ ID NOS: 5, 8 and 15. Oligonucleotide 2 hybridized with a DNA fragment which encodes an homologous sequence of SEQ ID NO: 7. Using oligonucleotides 4 and 5, it was only possible to isolate clones whose DNA fragments did not encode SEQ ID NOS: 10 and 12. This is why these oligonucleotides and the clones which had been isolated from the λZAP Express gene library were employed in a Southern Blot analysis, which permitted the unequivocal identification of DNA fragments which hybridized with the oligonucleotides, but not with the DNA fragments resulting from the screening. With these DNA fragments, in each case one sub-gene library was prepared in the λZAP Express vector, and each sub-gene library was screened with oligonucleotides 4 and 5. This allowed the identification of clones which carry DNA fragments encoding the sequences of SEQ ID NOS: 10 and 12. Partial digestion of H. pylori DNA using the restriction enzymes Sau3AI, Alul and f-aelll gave a DNA which was used for establishing gene libraries in the vector λTriplex (Clontech) . These gene libraries were used as starting material for isolating the complete genes of the above-described DNA fragments using standard methods. SEQ ID NO: 20 describes the DNA sequence which encodes the catalase of H. pylori . The nucleotide region 337 to 378 describes the hybridization site with oligonucleotide 1. The catalase gene of H. pylori has been described in 1996 by Stefan Odenbreit, Bjδrn Wieland and Rainer Haas (J. Bacteriol. 178, 6960-6967) and is therefore not new. However, when comparing the amino acid sequences of the catalases of Escheri chia coJi, Bacillus firmυs, B. subtilis A, B. subtilis B, rats, mice, cattle, humans, Staphylococcus violaceus, Haemophilus inflυenzae, B. fragilis, Pseudomonas mirabilis, B. pertussis and P. syringae with the amino acid sequence of H. pylori , it is possible to identify two C-terminal regions Cl (RDPKFNLAHIEKEFEVWNWDYRA) and C2 (EKHQKMMKDMHGKDMHHTKKKK) , which are specific to H. pyl ori catalase. These two peptides were synthesized using standard techniques, coupled to KLH and used for immunizing rabbits. These rabbits developed antibodies against the two peptides, which reacted in the Western Blot analysis with H. pylori catalase which had been produced by recombinant technique. These H. pyl ori- catalase-specific regions may conceivably be used for developing a vaccine which avoids the problem complex of autoimmune reactions or for the development of a diagnostic which reacts specifically with H. pylori catalase. SEQ ID NO: 21 describes a nucleotide sequence which was identified by hybridization with the oligonucleotide 2. The oligonucleotide hybridized with the sequence of nucleotide 1240 to 1284. This encodes a sequence which is homologous to the porin Hop C (Exner et al., 1995) and is identical with the published amino- terminal sequence EDDGGFFTVGYQLGQVMQDVQNPG in positions 1, 2, 3, 4, 9, 10, 11, 12, 14, 18 and 22. The porins Hop A, Hop B, Hop C and Hop D have identical amino acids in 9 positions of the 20 N-terminal amino acids (Exner et al . , 1995). In 8 of these positions, there are identical positions also in the sequence described in the present publication; in the 9th position, a conserved amino acid exchange is present (Val - lie) . It can thus be assumed that the protein described in the present publication is equally part of this group of the porins; it was therefore termed Hop X. On the basis of the homology data and on the basis of the N-terminal sequence determined and on the basis of the hydrophobicity of the N-terminal protein sequence deduced from the nucleic acid sequence, it can be concluded that the protein deduced has a signal sequence. The mature protein with 428 amino acids has a molecular weight of 47.3 kD and an isoelectric point of 10.0. A further open reading frame was found upstream of the gene which encodes Hop X. This further open reading frame encodes a protein which is homologous to Hop X (34% identity) and which was therefore termed Hop Y. The gene region found to date encodes the 361 C- terminal amino acids of the protein. The gene region as yet outstanding is currently being isolated using stan- dard techniques . We have thus identified a gene region of H. pylori which encodes at least two porins which are connected in series. SEQ ID NO: 22 describes a nucleotide sequence which was concomitantly isolated and sequenced during the screening process . The amino acid sequence deduced encodes the 392 C-terminal residues of a protein which shows a high homology with Hop X (33% identity) and Hop Y (28% identity) and which was therefore termed Hop Z. The gene region which encodes the N-terminal portion of the protein is currently being isolated. SEQ ID NO: 23 describes a DNA sequence which encodes a hitherto undescribed protein. The nucleotide region 696 to 767 describes the hybridization site with the oligonucleotide 6. On the basis of the N-terminal protein sequence which has been determined, in which it was not possible unequivocally to determine the amino acids in the first two positions, and on the basis of the hydrophobicity of the N-terminal protein sequence deduced from the nucleic acid sequence, it can be concluded that the protein deduced has a signal sequence of 17 amino acids. The mature protein of 231 amino acids has a molecular weight of 26.4 kD and an isoelectric point of 10.3. Thus, the molecular weight is quite close to the molecular weight of 28 kD which had been determined by SDS gel electrophoresis. The amino acid sequence deduced is homologous with the sequences of the proteins Hop X, Hop Y and Hop Z, for which the GCG Bestfit Programme determined identity values of 41%, 38% and 41%, respectively. The 28 kD protein thus also seems to be part of the family of the porins or porin-like proteins. SEQ ID NO: 24 describes a DNA sequence which encodes the non-heat-modifiable 50 kD membrane protein. This protein was first described by Exner et al., 1995, and an N-terminal sequence of the protein was determined. Using the approach described by us, we were then able to describe, with SEQ ID NO: 8, an N-terminal sequence which is identical to the sequence described by Exner et al. (1995) . With the aid of the oligonucleotide 3, which had been deduced using the method illustrated in Example 5 and had been used for screening a H. pylori gene library using the above-described methods, it was then possible to identify a DNA fragment which encodes the 50 kD membrane protein. Using other standard methods, it was then possible to determine the nucleic acid sequence described in SEQ ID NO: 24, which encodes a mature protein of 499 amino acids which has a molecular weight of 56.3 kD and an isoelectric point of 9.75. Due to the data of the N-terminal sequencing procedures and the hydrophobicity of the N-terminal sequence, a signal sequence of 29 amino acids is assumed. The amino acid residues 236 to 254 contain a hydrophobic region which is large enough to act as a transmembrane region. Based on such data and using standard methods for epitope analysis, it is possible to identify regions which might be presented on the surface of bacteria. Such regions might be used for developing a vaccine or a diagnostic. SEQ ID NO: 25 describes a DNA sequence 2825 bp in size which was identified by means of hybridization with oligonucleotide 4, which was deduced from SEQ ID NO: 10. Oligonucleotide 4 hybridized with the nucleotide region 897 to 923 of the described sequence of SEQ ID NO: 25. The protein has no signal sequence. The encoding region of SEQ ID NO: 25 codes for a protein of 399 amino acids with a molecular weight of 43.6 kD and an isoelectric point of 5.0. A search for homologous sequences using the BLASTP program (S. F. Altschul et al., 1990, J. Mol. Biol. 215, 403-410) identified the 42 kD antigen of H. pylori as the elongation factor TU. The maximum percentage of identity (89%) was found with the elongation factor TU from Wolinella succinogenes (W. Ludwig et al . , 1993, Antonie van Leeuwenhoek 64, 285- 305 ) . SEQ ID NO: 26 describes a DNA sequence 2182 bp in size which hybridizes with oligonucleotide 5, which had been deduced from SEQ ID NO: 12. Oligonucleotide 5 hybridized with a Sau3AI fragment (position 1 to 575) of the gene library starting from position 524. The screening of different DNA libraries with specific oligonucleotides allowed the isolation of the complete gene described in SEQ ID NO: 26. An amino acid sequence which is identical to the one from SEQ ID NO: 12 can be deduced from SEQ ID NO: 26. Both protein sequencing and the hydrophobicity of the N-terminal sequence deduced allow the conclusion that the antigen has a signal sequence. The mature protein consists of 328 amino acid residues with a molecular weight of 36.1 kD and an isoelectric point of 9.95. No homologous proteins were identified using the BLASTP program (S. F. Altschul et al., 1990) . The sequences described in SEQ ID NOS: 20 to 26 indicate nucleotide sequences which encode antigens of the H. pylori strain ATCC 43504. However, it is known for H. pylori that heterogeneity between identical antigens may exist amongst various strains. We therefore claim not only the sequences described in SEQ ID NOS: 21 to 26, but in addition also the sequences of other H. pylori strains which are homologous with the sequences described herein. Example 7 Identification and isolation of genes from H. pylori corresponding to the peptide sequences listed in Tables la-lc using the access to the genomic sequence The Institute for Genomic Research (TIGR) released the DNA sequence from H. pylori on 24th June 1997. This new information can be accessed on the internet at "www.tigr.org". Using the TBLASTN program (Altschul et al., 1997, Nucleic Acids Research 25, in press) the peptide sequences listed in Tables la-lc can be aligned to amino acid sequence data deduced from all six reading frames of the H. pylori strain 26695. Having access to the genomic DNA sequence, DNA sequences corresponding to the aligned amino acid sequences can be identified using GCG (Genetic Computer Group) programs. This approach is shown for SEQ ID NO: 19, for example. The sequence of SEQ ID NO: 19 aligned with a very similar sequence using the TBLASTN program. SEQ ID NO: 27 describes the nucleic acid sequence and deduced amino acid sequence from the coding region of a H. pylori gene (strain 26695) localised between position 843212 and 843691 of the genomic sequence. The protein has no signal sequence. The N-terminal sequence of SEQ ID NO: 19 is highly homologous to the N-terminal region of the deduced amino acid sequence from amino acid residue 1 to 15. Only one different amino acid residue is present at position 4: the nucleotide sequence found by the alignment encodes a Ser residue in this position instead of an Asn residue determined by N-terminal sequencing. This can be explained by strain specific differences. The identified nucleic acid sequence in SEQ ID NO: 27 codes for a protein of 159 amino acid residues with a molecular weight of 18.2 kD and an isoelectric point of 7.2. The molecular weight is very close to that of 17 kD determined from SDS polyacrylamide gel electrophoresis. A search for homologous sequences using the BLASTP program (S. F. Altschul et al., 1990) shows that the 17 kD antigen is very homologous to "hydroxymyristol- [acyl carrier protein] dehydratase" from different bacteria.
