Description: SUBTILISIN CARLSBERG VARIANTS HAVING DECREASED ADSORPTION AND INCREASED HYDROLYSIS TECHNICAL FIELD The present invention relates to novel enzyme variants useful in a variety of cleaning compositions, and the genes encoding such enzyme variants. BACKGROUND Enzymes make up the largest class of naturally occurring proteins. Each class of enzyme generally catalyzes (accelerates a reaction without being consumed) a different kind of chemical reaction. One class of enzymes known as proteases, are known for their ability to hydroiyze (break down a compound into two or more simpler compounds with the uptake of the H and OH parts of a water molecule on either side of the chemical bond cleaved) other proteins. This ability to hydroiyze proteins has been taken advantage of by incorporating naturally occurring and protein engineered proteases as an additive to laundry detergent preparations. Many stains on clothes are proteinaceous and wide-specificity proteases can substantially improve removal of such stains. Unfortunately, the efficacy level of these proteins in their natural, bacterial environment, frequently does not translate into the relatively unnatural wash environment. Specifically, protease characteristics such as thermal stability, pH stability, oxidative stability and substrate specificity are not necessarily optimized for utilization outside the natural environment of the enzyme. The amino acid sequence of the protease determines the characteristics of the protease. A change of the amino acid sequence of the protease may alter the properties of the enzyme to varying degrees, or may even inactivate the enzyme, depending upon the location, nature and/or magnitude of the change in the amino acid sequence. Several approaches have been taken to alter the wild-type amino acid sequence of proteases in an attempt to improve their properties, with the goal of increasing the efficacy of the protease in the wash environment. These approaches include altering the amino acid sequence to enhance thermal stability and to improve oxidation stability under quite diverse conditions. Despite the variety of approaches described in the art, there is a continuing need for new effective variants of proteases useful for cleaning a variety of surfaces. Objects of the Present Invention It is an object of the present invention to provide subtilisin Carlsberg enzyme variants having improved hydrolysis versus the wild-type of the enzyme. It is also an object of the present invention to provide cleaning compositions comprising these subtilisin enzyme variants. SUMMARY The present invention relates to subtilisin Carlsberg variants having a modified amino acid sequence of wild-type subtilisin Carlsberg amino acid sequence, the wild-type amino acid sequence comprising a first loop region, a second loop region, a third loop region, a fourth loop region and a fifth loop region; wherein the modified amino acid sequence comprises different amino acids than that occurring in wild-type subtilisin Carlsberg (i.e., substitution) at specifically identified positions in one or more of the loop regions whereby the subtilisin Carlsberg variant has decreased adsorption to, and increased hydrolysis of, an insoluble substrate as compared to the wild-type subtilisin Carlsberg. The present invention also relates to the genes encoding such subtilisin Carlsberg variants. The present invention also relates to compositions comprising such subtilisin Carlsberg variants for cleaning a variety of surfaces. DESCRIPTION I. Subtilisin Variants This invention pertains to subtilisin enzymes, in particular subtilisin Carlsberg, that have been modified by mutating the various nucleotide sequences that code for the enzyme, thereby modifying the amino acid sequence of the enzyme. The modified subtilisin enzymes (hereinafter, "subtilisin Carlsberg variants") of the present invention have decreased adsoφtion to and increased hydrolysis of an insoluble substrate as compared to the wild-type subtilisin. The present invention also pertains to the mutant genes encoding for such subtilisin Carlsberg variants. The subtilisin enzymes of this invention belong to a class of enzymes known as proteases. A protease is a catalyst for the cleavage of peptide bonds. One type of protease is a serine protease. A serine protease is distinguished by the fact that there is an essential serine residue at the active site. The observation that an enzyme's rate of hydrolysis of soluble substrates increases with enzyme concentration is well documented. It would therefore seem plausible that for surface bound substrates, such as is encountered in many cleaning applications, the rate of hydrolysis would increase with increasing surface concentration. This has been shown to be the case. (Brode, P.F. Ill and D. S. Rauch, LANGMUIR, "Subtilisin BPN': Activity on an Immobilized Substrate", Vol. 8, pp. 1325-1329 (1992)). In fact, a linear dependence of rate upon surface concentration was found for insoluble substrates when the surface concentration of the enzyme was varied. (Rubingh, D. N. and M. D. Bauer, "Catalysis of Hydrolysis by Proteases at the Protein-Solution Interface," in POLYMER SOLUTIONS, BLENDS AND INTERFACES, Ed. by I. Noda and D. N. Rubingh, Elsevier, p. 464 (1992)). Surprisingly, when seeking to apply this principle in the search for variant proteases which give better cleaning performance, we did not find that enzymes which adsorb more give better performance. In fact, we surprisingly determined the opposite to be the case: decreased adsorption by an enzyme to a substrate resulted in increased hydrolysis of the substrate (i.e., better cleaning performance). While not wishing to be bound by theory, it is believed that improved performance, when comparing one variant to another, is a result of the fact that enzymes which adsorb less are also less tightly bound and therefore more highly mobile on the surface from which the insoluble protein substrate is to be removed. At comparable enzyme solution concentrations, this increased mobility is sufficient to outweigh any advantage that is conferred by delivering a higher concentration of enzyme to the surface. The mutations described herein are designed to change (i.e., decrease) the adsorption of the enzyme to surface-bound soils. In subtilisin Carlsberg, certain amino acids form exterior loops on the enzyme molecule. For purposes of discussion, these loops shall be referred to as first, second, third, fourth and fifth loop regions. Specifically, positions 58-65 form the first loop region; positions 94-106 form the second loop region; positions 125-132 form the third loop region; positions 153-166 form the fourth loop region; positions 186-190 form the fifth loop region; and positioins 199-219 form the sixth loop region (position numbering analagous to positions in the amino acid sequence for wild-type subtilisin subtilisin Carlsberg (SEQ ID NO:1 )). It believed that these loop regions play a significant role in the adsorption of the enzyme molecule to a surface-bound peptide, and specific mutations in one or more of these loop regions will have a significant effect on this adsoφtion. While not wishing to be bound by theory, it is believed that the loop regions are important to the adsoφtion of the subtilisin Carlsberg molecule for at least two reasons. First, the amino acids which comprise the loop regions can make close contacts with any surfaces to which the molecule is exposed. Second, the proximity of the loop regions to the active-site and binding pocket of the subtilisin Carlsberg molecule gives them a role in the catalytically productive adsoφtion of the enzyme to surface-bound substrates (peptides/protein soils). As used herein, "variant" means an enzyme having an amino acid sequence which differs from that of wild-type. As used herein, "mutant subtilisin Carlsberg gene" means a gene coding for a subtilisin Carlsberg variant. As used herein, "wild-type subtilisin Carlsberg" refers to a subtilisin enzyme represented by SEQ ID NO:1. The amino acid sequence for subtilisin Carlsberg is further described by Smith, E.L., Delange, R.J Evans, W.H., Landon, M., and Markland, F.S., J. BIOL. CHEM., Vol. 243, pp. 2184- 2191 (1968), in∞φorated herein by reference. As used herein, the term "subtilisin Carlsberg wild-type amino acid sequence" encompasses SEQ ID NO:1 as well as SEQ ID NO:1 having modifications to the amino acid sequence other than at any of positions 58- 65, 94-106, 125-132, 153-166, 186-190 and 199-219. As used herein, "more hydrophilic amino acid" refers to any other amino acid having greater hydrophiiicity than a subject amino acid with reference to the hydrophiiicity table below. The following hydrophiiicity table (Table 1) lists amino acids in descending order of increasing hydrophiiicity (see Hopp, T.P., and Woods, K.R., "Prediction of Protein Antigenic Determinants from Amino Acid Sequences", PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCE USA, Vol. 78, pp. 3824-3828, 1981 , incorporated herein by reference). TABLE 1 Amino Acid Hydrophiiicity Value Tφ -3.4 Phe -2.5 Tyr -2.3 Leu, lie -1.8 Val -1.5 Met -1.3 Cys -1.0 Ala, His -0.5 Thr -0.4 Pro, Gly -0.0 Gin, Asn 0.2 Ser 0.3 Arg + , Lys + , Glu" Asp- 3.0 Table 1 also indicates which amino acids carry a charge (this characteristic being based on a pH of from about 8-9). The positively charged amino acids are Arg and Lys, the negatively charged amino acids are Glu and Asp, and the remaining amino acids are neutral. In a preferred embodiment of the present invention, the substituting amino acid is either neutral or negatively charged, more preferably negatively charged (i.e., Glu or Asp). Therefore, for example, the statement "substitute Gin with an equally or more hydrophilic amino acid which is neutral or has a negative charge" means Gin would be substituted with Asn (which is equally hydrophilic to Gin), or Ser, Glu or Asp (which are more hydrophilic than Gin); each of which are neutral or have a negative charge, and have a greater hydrophiiicity value as compared to Gin. Likewise, the statement "substitute Pro with a more hydrophilic amino acid which is neutral or has a negative charge" means Pro would be substituted with Gin, Asn, Ser, Glu or Asp. In one embodiment of the present invention, the subtilisin Carlsberg variant has a modified amino acid sequence of subtilisin Carlsberg wild-type amino acid sequence, wherein the wild-type amino acid sequence comprises a substitution at one or more positions in one or more of the first loop region, the second loop region, the third loop region, the fourth loop region, the fifth loop region or the sixth loop region; whereby the subtilisin Carlsberg variant has decreased adsoφtion to, and increased hydrolysis of, an insoluble substrate as compared to the wild-type subtilisin Carlsberg. In a preferred embodiment of the present invention, the substituting amino acid for one or more of the positions in one or more of the loop regions is, with reference to Table 1 , neutral or negatively charged and equally or more hydrophilic, preferably more hydrophilic, than the amino acid at the subject position in the wild-type amino acid sequence.

Preparation of enzyme variants Example 1 Mutant subtilisin Carlsberg Genes A phagemid ("CP") containing the wild type subtilisin Carlsberg gene is constructed. The 2.8 Kbp Pvu II restriction enzyme fragment of plasmid pUC119, (Vieira, J. and Messing, J., "Production of Single-Stranded Plasmid DNA", 153 METHODS IN ENZYMOLOGY 3-11 (1989)) is cloned into the Pvu II site of plasmid pUB110 (Bacillus Genetic Stock Center, Columbus, OH 1E9). The pUC119-pUB110 hybrid plasmid is named pJMA601. Into the Bam H1 restriction site of pJMA601 is cloned the polymerase chain reaction - amplified subtilisin Carlsberg gene giving CP. Phagemid CP is transformed into Escherichia coli ung-strain CJ236 and a single stranded uracil-containing DNA template is produced using the VCSM13 helper phage (Kunkel, T.A., J.D. Roberts and R.A. Zakour, "Rapid and efficient site-specific mutagenesis without phenotypic selection", METHODS IN ENZYMOLOGY, Vol. 154, pp. 367-382, (1987); as modified by Yuckenberg, P.D., F. Witney, J. Geisselsoder and J. McClary, "Site-directed in vitro mutagenesis using uracil-containing DNA and phagemid vectors", DIRECTED MUTAGENESIS - A PRACTICAL APPROACH, ed. M.J. McPherson, pp. 27-48, (1991); both of which are incoφorated herein by reference). A single primer site-directed mutagenesis modification of the method of Zoller and Smith (Zoller, M.J., and M. Smith, "Oiigonudeotide-directed mutagenesis using M13-derived vectors: an efficient and general procedure for the production of point mutations in any fragment of DNA", NUCLEIC ACIDS RESEARCH, Vol. 10, pp. 6487-6500, (1982), incorporated herein by reference) is used to produce all mutants (basically as presented by Yuckenberg, et al., 1991 , above). Oligonucleotides are made using an Applied Biosystem Inc. 380B DNA synthesizer. Mutagenesis reaction products are transformed into Escherichia coli strain MM294 (American Type Culture Collection E. Coli. 33625). Ail mutants are confirmed by DNA sequencing and the isolated DNA is transformed into the Bacillus subtilis expression strain BG2036 (Yang, M. Y., E. Ferrari and D. J. Henner, (1984), "Cloning of the Neutral Protease Gene of Bacillus subtilis and the Use of the Cloned Gene to Create an In Vitro-derived Deletion Mutation", JOURNAL OF BACTERIOLOGY, Vol. 160, pp. 15-21). For some of the loop mutants a modified CP with a frameshift-stop codon mutation in the corresponding loop is used to produce the uracil template. Oligonucleotides are designed to restore the proper reading frame and to encode for random substitutions at positions 56, 59, 60, 61, 62, 64, 65, 94, 95, 96, 97, 98, 99, 100, 101 , 102, 103, 104, 105, 106, 125, 126, 127, 128, 129, 130, 131, 132, 153, 154, 155, 156, 157, 158, 159, 160, 161 , 162, 163, 164, 165, 166, 186, 187, 188, 189, 190, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218 and/or 219 (equimolar and/or variable mixtures of all four nucleotides for all three bases at these codons). Mutations that correct for the frameshift-stop and produce a functional enzyme are identified by their ability to digest casein. The random substitutions are determined by DNA sequencing. [Example 2 Fermentation The Bacillus subtilis cells (BG2036) containing a subtilisin mutant of interest are grown to mid-log phase in a one liter culture of LB-glucose broth and inoculated into a Biostat ED fermenter (B. Braun Biotech, Inc., Allentown, Pennsylvania) in a total volume of 10 liters. The fermentation media contains Yeast Extract, starch, antifoam, buffers and trace minerals (see FERMENTATION: A PRACTICAL APPROACH, Ed. B. McNeil and L. M. Harvey, 1990). The broth is kept at a constant pH of 7.0 during the fermentation run. Chloramphenical is added for antibiotic selection of mutagenized plasmid. The cells are grown overnight at 37 β C to an Agoo °f about 60 and harvested. Example 3 Purification The fermentation broth is taken through the following steps to obtain pure enzyme. The broth is cleared of Bacillus subtilis cells by centrifugation, and clarified by removing fine particulates with a 100K cutoff membrane. This is followed by concentration on a 10K cutoff membrane, and flow dialysis to reduce the ionic strength and adjust the pH to 5.5 using 0.025M MES buffer (2-(Λ/-moφholino)ethanesulfonic acid). The enzyme is further purified by loading it onto either a cation exchange chromatography column or an affinity adsoφtion chromatography column and eluting it from the column with a NaCl or a propylene glycol gradient (see Scopes, R. K, PROTEIN PURIFICATION PRINCIPLES AND PRACTICE, Springer-Verlag, New York (1984), in∞φorated herein by reference). The pNA assay (Del Mar, E.G., C. Largman, J.W. Brodrick and M.C. Geokas, ANAL. BIOCHEM., Vol. 99, pp. 316-320, (1979), incorporated herein by reference) is used to determine the active enzyme concentration for fractions collected during gradient elution. This assay measures the rate at which p-nitroaniline is released as the enzyme hydrolyzes the soluble synthetic substrate, succinyl-alanine-alanine-proline-phenylalanine-p- nitroanilidβ (sAAPF-pNA). The rate of production of yellow color from the hydrolysis reaction is measured at 410 nm on a spectrophotometer and is proportional to the active enzyme concentration. In addition, absorbance measurements at 280 nm are used to determine the total protein concentration. The active enzyme total-protein ratio gives the enzyme purity, and is used to identify fractions to be pooled for the stock solution. To avoid autolysis of the enzyme during storage, an equal weight of propylene glycol is added to the pooled fradions obtained from the chromatography column. Upon completion of the purification procedure the purity of the stock enzyme solution is checked with SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) and the absolute enzyme concentration is determined via an adive site titration method using trypsin inhibitor type ll-T: turkey egg white purchased from Sigma Chemical Company (St. Louis, Missouri). The measured conversion fadors will show which changes made in the enzyme molecule at the various positions result in the enzyme variant having increased adivity over the wild-type, against the soluble substrate pNA. In preparation for use, the enzyme stock solution is eluted through a Sephadex-G25 (Pharmacia, Piscataway, New Jersey) size exclusion column to remove the propylene glycol and exchange the buffer. The MES buffer in the enzyme stock solution is exchanged for 0.1 M Tris buffer (Tris(hydroxymethyl-aminomethane) containing 0.01 M CaCl2 and pH adjusted to 8.6 with HCI. All experiments are carried out at pH 8.6 in Tris buffer thermostated at 25°C. H. Charaderization of eπzvme variants Example 4 Model Surface Preparation Aminopropyl controlled pore glass (CPG) purchased from CPG Inc. (Fairfield, New Jersey) is used as a support for covalently attaching the sAAPF-pNA substrate purchased from Bachem, Inc. (Torrence, California). The reaction is carried out in dimethyl sulfoxide and (1 -ethyl -3-[3- (dimethylamino)propyl] carbodiimide hydrochloride) (EDC) is used as a coupling agent. Upon completion (monitored by pNA assay), the excess solvent is removed, and the CPG:sAAPF-pNA is rinsed with dimethyl sulfoxide (DMSO) and doubly-distilled water. This is followed by oven drying with a N2 purge at about 70°C. The reaction scheme and preparation of the immobilized substrate are conducted as described by Brode, P.F. Ill, and D.S. Rauch, "Subtilisin BPN': Adivity on an Immobilized Substrate," LANGMUIR, Vol. 8, p. 1325-1329, (1992), incoφorated herein by reference. The CPG surface will have 62,000 ± 7,000 pNA molecules/μm 2 . The surface area will remain unchanged from the value of 50.0rrι2/g reported by CPG Inc. for the CPG as received. This suggests that the procedure used to add sAAPF-pNA to CPG does not damage the porous structure (mean diameter is 486 A). Example 5 Surface Hvdrolvsis Assay Using CPG:sAAPF-pNA, adsoφtion of an enzyme variant and hydrolysis of a CPG-bound peptide can be measured in a single experiment. A small volume of enzyme variant stock solution is added to a flask containing Tris buffer and CPG:sAAPF-pNA which has been degassed. The flask is shaken on a wrist-action shaker for a period of 90 minutes during which the shaker is stopped at various time intervals (for example, every 2 minutes during the early stages of adsoφtion hydrolysis - e.g., the first 20 minutes - and every 10 minutes towards the end of the experiment). The CPG:sAAPF-pNA is allowed to settle and the solution is sampled. Both the experimental procedure and the calculation of the adsoφtion and hydrolysis are conducted as described by Brode et al., 1992, above. All enzymes are monitored for stability against autolysis and should show no appreciable autolytic loss over the time course of this experiment. Therefore, enzyme adsoφtion can be determined by measuring solution depletion. The difference between the initial enzyme variant concentration and the concentration measured at each individual time point gives the amount of enzyme variant adsorbed. The amount of pNA hydrolyzed from the surface is measured by taking an absorbance reading on an aliquot of the sample at 410 nm. The total amount of pNA hydrolyzed is calculated by adding the amount sampled and the amount remaining in the flask. This value is corrected by subtracting the amount of pNA that is hydrolyzed by Tris buffer at pH 8.6 when no enzyme is present. This base-hydrolysis ranges from 7-29% of the total hydrolysis depending on the efficiency of the enzyme. Example 6 Soluble Substrate Kinetic Analysis The rates of hydrolysis of the soluble substrate sAAPF-pNA are monitored by measuring the adsorbance increase as a function of time at 410 nm on a DU-70 spectrophotometer. The enzyme concentration is held constant and is prepared to be in the range of 6-10 nanomolar while the substrate concentration is varied from 90-700 μM sAAPF-pNA for each kinetic determination. An adsorbance data point is taken each second over a period of 900 seconds and the data are transferred to a LOTUS™ spreadsheet (Lotus Development Coφoration, Cambridge, Massachusetts). Analysis for kinetic parameters is conduded by the standard Lineweaver Burk analysis in which the data in the initial part of the run (generally the first minute) are fit to a linear regression curve to give v 0 . The v 0 and s 0 data are plotted in the standard inverse fashion to give KM and k^. I. Example subtilisin Carlsberg variants subtilisin Carlsberg variants of the present invention which have decreased adsoφtion to and increased hydrolysis of surface bound substrates are exemplified in Tables 3-36, below. In describing the specific mutations, the original amino acid occurring in wild-type is given first, the position number second, and the substituted amino acid third.

Cleaning Compositions In another embodiment of the present invention, an effective amount of one or more of the enzyme variants are induded in compositions useful for cleaning a variety of surfaces in need of proteinaceous stain removal. Such cleaning compositions include detergent compositions for cleaning hard surfaces, unlimited in form (e.g., liquid and granular); detergent compositions for cleaning fabrics, unlimited in form (e.g., granular, liquid and bar formulations); dishwashing compositions (unlimited in form); oral cleaning compositions, unlimited in form (e.g., dentifrice, toothpaste and mouthwash formulations); denture cleaning compositions, unlimited in form (e.g., liquid, tablet); and contact lens cleaning compositions, unlimited in form (e.g., liquid, tablet). The cleaning compositions also comprise, in addition to the subtilisin Carlsberg variants described hereinbefore, one or more cleaning composition materials compatible with the protease enzyme, the term "cleaning composition material", as used herein, means any liquid, solid or gaseous material seleded for the particular type of cleaning composition desired and the form of the product (e.g., liquid, granule, bar, spray, stick, paste, gel), which materials are also compatible with the subtilisin Carlsberg variant used in the composition, the specific seledion of cleaning composition materials are readily made by considering the surface material to be cleaned, the desired form of the composition for the cleaning condition during use (e.g., through the wash detergent use). The term "compatible", as used herein, means the cleaning composition materials do not reduce the proteolytic adivity of the subtilisin Carlsberg variant to such an extent that the protease is not effedive as desired during normal use situations. Specific cleaning composition materials are exemplified in detail hereinafter. As used herein, "effedive amount of enzyme variant" refers to the quantity of enzyme variant necessary to achieve the enzymatic adivity necessary in the specific deaning composition. Such effedive amounts are readily ascertained by one of ordinary skill in the art and is based on many fadors, such as the particular enzyme variant used, the cleaning application, the specific composition of the cleaning composition, and whether a liquid or dry (e.g., granular, bar) composition is required, and the like. Preferably the deaning compositions comprise from about 0.0001 % to about 10% of one or more enzyme variants of the present invention, more preferably from about 0.001% to about 1%, more preferably still from about 0.01% to about 0.1%. Several examples of various cleaning compositions wherein the enzyme variants may be employed are discussed in further detail below. All parts, percentages and ratios used herein are by weight unless otherwise specified. As used herein, "non-fabric cleaning compositions" include hard surface cleaning compositions, dishwashing compositions, oral cleaning compositions, denture cleaning compositions and contact lens cleaning compositions. A. Cleaning Compositions for Hard Surfaces. Dishes and Fabrics The enzyme variants of the present invention can be used in a variety of detergent compositions where high sudsing and good insoluble substrate removal are desired. Thus the enzyme variants can be used with various conventional ingredients to provide fully-formulated hard-surface cleaners, dishwashing compositions, fabric laundering compositions and the like. Such compositions can be in the form of liquids, granules, bars and the like. Such compositions can be formulated as modem "concentrated" detergents which contain as much as 30%-60% by weight of surfadants. The cleaning compositions herein can optionally, and preferably, contain various anionic, nonionic, zwitterionic, etc., surfadants. Such surfadants are typically present at levels of from about 5% to about 35% of the compositions. Nonlimiting examples of surfadants useful herein include the conventional C-n-C-is alkyl benzene sulfonates and primary and random alkyl sulfates, the C < ιo-C*ι.8 secondary (2,3) alkyl sulfates of the formulas CH 3 (CH 2 )x(CHOSθ3)-M + )CH 3 and CH 3 (CH 2 )y(CHOS0 3 -M + ) CH 2 CH 3 wherein x and (y+1) are integers of at least about 7, preferably at least about 9, and M is a water-solubilizing cation, espe ally sodium, the C*ιo- C-)8 alkyl alkoxy sulfates (especially EO 1-5 ethoxy sulfates), Cιrj-Ci8 a'kyl alkoxy carboxylates (especially the EO 1-5 ethoxycarboxylatβs), the C-jrj- C*i8 alkyl polyglycosides, and their corresponding sulfated polyglycosides, C- * 2-C-|8 alpha-sutfonated fatty acid esters, C*|2- *18 a| M and alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), Cι 2 -Cι,8 betaines and sulfobetaines ("sultaines"), C10-C18 amine oxides, and the like. The alkyl alkoxy sulfates (AES) and alkyl alkoxy carboxylates (AEC) are preferred herein. (Use of such surfadants in combination with the aforesaid amine oxide and/or betaine or sultaine surfadants is also preferred, depending on the desires of the formulator.) Other conventional useful surfadants are listed in standard texts. Particularly useful surfadants indude the C10-C18 N-methyl glucamides disclosed in US Patent δ, 194,639, Connor et al., issued March 16, 1993, incorporated herein by reference. A wide variety of other ingredients useful in detergent cleaning compositions can be included in the compositions herein, including other adive ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations, etc. If an additional increment of sudsing is desired, suds boosters such as the C10-C16 alkolamides can be incorporated into the compositions, typically at about 1 % to about 10% levels. The C10-C14 monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjund surfadants such as the amine oxides, betaines and sultaines noted above is also advantageous. If desired, soluble magnesium salts such as MgCI 2 , MgS04, and the like, can be added at levels of, typically, from about 0.1% to about 2%, to provide additionally sudsing. The liquid detergent compositions herein can contain water and other solvents as carriers. Low molecular weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfadants, but polyols such as those containing from about 2 to about 6 carbon atoms and from about 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1 ,2-proρanediol) can also be used. The compositions may contain from about 5% to about 90%, typically from about 10% to about 60% of such carriers. The detergent compositions herein will preferably be formulated such that during use in aqueous cleaning operations, the wash water will have a pH between about 6.8 and about 11.0. Finished produds thus are typically formulated at this range. Techniques for controlling pH at recommended usage levels indude the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art. When formulating the hard surface cleaning compositions and fabric deaning compositions of the present invention, the formulator may wish to employ various builders at levels from about δ% to about 60% by weight. Typical builders indude the 1-10 micron zeolites, polycarboxylates such as citrate and oxydisuccinates, layered silicates, phosphates, and the like. Other conventional builders are listed in standard formularies. Likewise, the formulator may wish to employ various additional enzymes, such as cellulases, lipases, amylases and proteases in such compositions, typically at levels of from about 0.001% to about 1% by weight. Various detersive and fabric care enzymes are well-known in the laundry detergent art. Various bleaching compounds, such as the percarbonates, perborates and the like, can be used in such compositions, typically at levels from about 1% to about 15% by weight. If desired, such compositions can also contain bleach activators such as tetraacetyl ethylenediamine, nonanoyloxybenzene sulfonate, and the like, which are also known in the art. Usage levels typically range from about 1% to about 10% by weight. Various soil release agents, especially of the anionic oligoester type, various chelating agents, especially the aminophosphonates and ethylenediaminedisuccinates, various clay soil removal agents, especially ethoxylated tetraethylene pentamine, various dispersing agents, especially polyacrylatθs and polyasparatates, various brighteners, especially anionic brighteners, various suds suppressors, especially silicones and secondary alcohols, various fabric softeners, especially smectite clays, and the like can all be used in such compositions at levels ranging from about 1 % to about 35% by weight. Standard formularies and published patents contain multiple, detailed descriptions of such conventional materials. Enzyme stabilizers may also be used in the cleaning compositions. Such enzyme stabilizers indude propylene glycol (preferably from about 1 % to about 10%), sodium formate (preferably from about 0.1% to about 1%) and calcium formate (preferably from about 0.1% to about 1%). 1. Hard surface cleaning compositions As used herein "hard surface cleaning composition" refers to liquid and granular detergent compositions for cleaning hard surfaces such as floors, walls, bathroom tile, and the like. Hard surface cleaning compositions of the present invention comprise an effedive amount of one or more enzyme variants of the present invention, preferably from about 0.001% to about 10%, more preferably from about .01% to about 5%, more preferably still from about .06% to about 1 % by weight of adive enzyme of the composition. In addition to comprising one or more of the enzyme variants, such hard surface cleaning compositions typically comprise a surfadant and a water-soluble sequestering builder. In certain specialized produds such as spray window cleaners, however, the surfadants are sometimes not used since they may produce a filmy/streaky residue on the glass surface. The surfadant component, when present, may comprise as little as 0.1% of the compositions herein, but typically the compositions will contain from about 0.25% to about 10%, more preferably from about 1% to about 5% of surfadant. Typically the compositions will contain from about 0.5% to about 50% of a detergency builder, preferably from about 1% to about 10%. Preferably the pH should be in the range of about 8 to 12. Conventional pH adjustment agents such as sodium hydroxide, sodium carbonate or hydrochloric acid can be used if adjustment is necessary. Solvents may be included in the compositions. Useful solvents include, but are not limited to, glycol ethers such as diethyleneglycol monohexyl ether, diethyleneglycol monobutyl ether, ethyleneglycol monobutyl ether, ethyleneglycol monohexyl ether, propyleneglycol monobutyl ether, dipropyleneglycol monobutyl ether, and diols such as 2,2,4-trimethyl-l ,3-pentanediol and 2-ethyl-1,3-hexanediol. When used, such solvents are typically present at levels of from about 0.5% to about 15%, preferably from about 3% to about 11%. Additionally, highly volatile solvents such as isopropanol or ethanol can be used in the present compositions to facilitate faster evaporation of the composition from surfaces when the surface is not rinsed after "full strength" application of the composition to the surface. When used, volatile solvents are typically present at levels of from about 2% to about 12% in the compositions.
