DXA 2 183, 1983 or through the use of synthetic nucleic acid strands The products of mutant genes can be readily tested for multifunctional activity The nucleic acid sequences can be further mutated, for example, to incorporate useful restnction sites See Maniatis et al Molecular Cloning, a Laboratory Manual (Cold Spnng Harbor Press. 1989) Such restnction sites can be used to create "cassettes", or regions of nucleic acid sequence that are facilely substituted using restriction enzy mes and gation reactions The cassettes can be used to substitute svnthetic sequences encoding mutated multifunctional protein ammo acid sequences The multifunctional protein-encoding sequence can be, for instance, substantially or fully synthetic See, for example, Goeddel et al , Proc Nad Acad. Set USA. 76. 106-110. 1979 For recombinant expression purposes, codon usage preferences for the organism in which such a nucleic acid is to be expressed are advantageously considered in designing a s nthetic multifunctional protein- encoding nucleic acid Since the nucleic acid code is degenerate, numerous nucleic acid sequences can be used to create the same amino acid sequence Further, with an altered amino acid sequence, numerous methods are known to delete a sequence from or mutate nucleic acid sequences that encode a polvpeptide and to confirm the function of the polypeptides encoded by these deleted or mutated sequences Accordingly, the invention also relates to a mutated or deleted version of a multifunctional protein nucleic acid that encodes a polvpeptide that retains multifunctional protein activity Conservative mutations of the naturally occumng isoforms are preferred for engineered vanants Such conservative mutations include mutations that switch one ammo acid for another within one of the following groups 1 Small aliphatic, nonpolar or slightly polar residues Ala, Ser, Thr, Pro and Gly , 2 Polar, negatively charged residues and their amides Asp, Asn, Glu and Gin. 3 Polar, positively charged residues' His, Arg and Lys, 4 Large aliphatic, nonpolar residues' Met, Leu, He, Val and Cys, and 5 Aromatic residues Phe, Tyr and Trp A prefened listing of conservative substitutions is the following Original Residue Substitution Ala Gly, Ser Arg Lys Asn Gin, His Asp Glu Cys Ser Gin Asn Glu Asp lie Leu, Val Leu He.

E coli BL21 (DE3) pLYS S having a chromosomal copy of the T7 polymerase gene under lacUV5 control Expression was induced by the addition of 1 mM EPTG at an optical density of 0 5 at wavelength 600 The cells were harvested after 2 hours at an optical density of 1 0 The recombinant protein was insoluble in the lysate and after harvesting, it was washed and dissolved in 6 M urea Refolding of the recombinant protein was earned out by 200-fold dilution using a buffer containing 100 mM tns HCl pH 9 5, 100 mM CaCl.,, 0 3 mM oxidized glutathione and 3 mM reduced glutathione, followed by stirnng overnight at 4°C Example 3. A fragment from the p62 clone that encodes ammo acids 56 to 300 and the stop codon (see SEQ ID NOs 1 an 4) was excised and inserted it into a pET-23c expression vector Note that this clone excludes the cvsteine required to form a disulfide link to a light chain The encoded protein was expressed in E coli strain BL2 l(DE3)pLysS, which yielded an insoluble matenal The insoluble matenal was dissolved in 6 M urea, and re-folded by a 200-fold dilution into an aqueous solution buffered at pH 9 5, containing 0 1 mM CaCl and oxidized/reduced glutathione The resulting solution was concentrated to recover the recombinant protein The recombinant protein was shown to cleave the model substrate succιnyl-ala-ala-pro-phe-/>- nitroarulide, thereby demonstrating its proteolytic activity The proteolytic activity was inhibited by the protease inhibitor Eg n Example 4. The multifunctional hydrolase denved from knll that is used in the context of the present invention is obtained from the antarctic knll species, Euphausia superba A prefened procedure for extraction, punfication and formulation into a bulk active formulation is achieved by the four step process outlined below Activity of PHM-101 was monitored in accordance with the procedure set forth at Example 7 The multifunctional hydrolase product resulting from the following procedure has been labeled PHM-101 , and displays an N-terminal sequence of I-V-G-G-N/M-E-V-T-P-H-A-Y-P-W-Q-V-G- L-F-I-D-D-M-Y-F (SEQ ID NO 52) Production of Freeze-dπed PHM-101 (Nominal Batch 100kg Knll) Step Material Activitv (UVYield (%) Knll 1 Extraction Microfiltered 200.000 100 Extract 2 Amon Exchange Chromatography DEAE Eluate 150,000 75 3 Affinity Chromatography PHM-101 Solution 125,000 83 Viral Filter Freeze-dry 80 Freeze-dned PHM-101 100,000 Krill Fishing and Supply The Knll used for the present invention were supplied by the established Japanese fishing company, Nissui In order to prevent spoiling (including auto lysis by the digestive enzymes), on board ship the knll were washed with seawater. packed into plastic bags containing approximately 12 5 kg, placed into labeled boxes indicating the date caught (two bags per box), flash frozen at a temperature of -40°C and so stored until thawed for extraction In accordance with a prefened aspect, only knll caught in December and January were used as this has been shown to be the time when the digestive enzyme activ lty is highest and pid content is lowest, thus making extraction maximally efficient PHM-101 Extraction, Purification and Formulation. The production process used standard protein separation and punfication techniques and equipment Four 25kg boxes of frozen knll were transfened from the bulk freezer store to a chest freezer After checking that the knll were in good condition, they were removed from their outer boxes, placed in trav s and allowed to defrost slowly overnight in the cold room at 4°C The next morning, the now partly defrosted knll were removed from their plastic wrapping, separated into small lumps and added to 400 litres of potable water in the extraction tank Here the material was gently stined for at least an hour until all the ice and lumps disappeared At vanous stages in the process samples were taken for analysis and stored indefinitely or at least until the satisfactory completion of the run The analyses conducted during the process are outlined below The crude extract was then separated from the solid waste by passing it through a coarse rotating drum sieve This fine extract was then pumped into a tall insulated sedimentation tank, where it was left overnight to allow the heavier components to sink to the bottom The next morning the supernatant was run off into an insulated holding tank, from where it was pumped to the microfiltration rig and the sediment was discarded The microfiltration ng used is a standard piece of equipment from Milhpore and is specifically designed for pharmaceutical processing Essentially this rig pumps the supernatant through a 2 micron filter arrav to remov e particulate debns, thus giving a clear solution for application to the first chromatography column The microfiltered extract was pumped through into a clean room area, where it was stored overnight in an insulated holding tank The first purification step in the process was a standard anionic exchange chromatography step, using an axial flow column containing ten litres of standard DEAE-sepharose. purchased from Pharmacia (Uppsala, Sweden) The column was equilibrated using a flow rate of about 120 liters per hour and not less than 5 column volumes of 20 mM Tπs-HCl buffer. pH 7 5 (Buffer A) After various standard preparation steps required to place the microfiltered extract into an appropnate volume, concentration, and salt content, the microfiltered extract was pumped onto the equilibrated DEAE-sepharose column using Buffer A, which is designed to selectively bind molecules with overall negative charge Other unwanted molecules passed through and were discarded after flowing 120 liters per hour with 10 +/- 3 column volumes of 10 mM Tns-HCl, 0 30 M NaCl buffer. pH 7 5 (Buffer B) By then washing the column at a rate of 60 liters per hour with approximately 4 column volumes of 10 mM Tns-HCl, 0 50 NaCl buffer, pH 7 5 (Buffer C), the PHM-101 is selectively displaced and collected from the column in three fractions This is refened to as the DEAE-Eluate Other unwanted molecules were left behind These unwanted molecules were also washed from the column and discarded by flowing 5 column volumes of 10 mM Tns-HCl, 1 00 M NaCl buffer, pH 7 5 (Buffer D), followed by 2 column volumes of 1 M NaOH, at a flow rate of about 120 liters per hour, allowing the column to stand without any flow for about 1 to about 24 hours, and then washing with 10 column volumes of distilled water, finally equilibrating the column with Buffer A as above, making the column readv for re-use Tvpically such a column is re-usable ten times before the sepharose is replaced The second step in the punfication process was an affinity chromatography step, which exploits the substrate-binding preferences of various enzymes for particular chemical groups The column used consists of a standard axial chromatography column, packed with 500 ml of sepharose to which has been attached a hgand having the structure aminophenylboronate Alternatively, for example, an agarose chromatography material could be used, such as Agarose 6XL, which is available commercially Using a flow rate of approximately 250 ml per minute, the column was equilibrated with 10 +/- 5 column volumes of Buffer C Thereafter, the DEAE-eluate was pumped onto the affinity column which specificallv binds seπne-protease enzvmes like PHM-101 using a flow rate of approximately 200 ml per minute, and continuing to wash the thus loaded column with 10 +/- 5 column volumes of Buffer C Contaminants that do not bind to the column and were discarded to waste, including those dislodged by further washing of the column with ( 1) 10 +/- 5 column olumes of 50 mM Tns-HCl 5 M CaCl; buffer. pH 7 5 (Buffer E) also at a rate of about 200 ml per minute, and (2) 1 +/- 0 8 column v olume of 10 mM Glycine-citrate 1 0 mM CaCL buffer, pH 7 4 (Buffer F) at a rate of about 100 ml per minute By then washing the column with about 4 column volumes of 10 mM Glvcine-citrate 1 0 mM CaCL, 200 mM Sorbitol buffer, pH 7 4 (Buffer G) at a rate of about 100 ml per minute, PHM- 101 -containing solution is displaced and collected Other unwanted molecules are left behind These unwanted molecules are subsequently washed from the column using the following senes of washes Wash 1, 5 column volumes of 30% v/v 2- propanol, 0 2 M NaOH followed by 5 column volumes of purified water, at 250 ml per minute. Wash 2. 5 column volumes of 0 1 M HCl followed by 5 column volumes of punfied water at 250 ml per minute. Wash 3, 5 column volumes of 50 mM NaOH followed by 5 volumes of punfied water, at 250 ml per hour, and Wash 4, 5 column volumes of 25% ethanol/75% 0 1 M NaCl, at 250 ml per hour Typically such a column is re-usable at least ten times before the sepharose is replaced To minimize the bioburden of the PHM-101 solution, it was filtered twice in a stenle cabinet using aseptic handling technique The first is a step designed to remove viruses and uses a commercially available virus filter, namely Planova 15 virus filter designed for the purpose The second, uses a commercially available 2 micron filter, using a vacuum pump to pass the filtered PHM-101 solution therethrough Before and after each filtration the mtegntv of each filter unit was tested and the material was only released if both tests were passed The filtered solution was aseptically filled into a stenle container and labeled before being removed from the stenle cabinet and stored in a chest freezer reser ed for the storage of filtered PHM-101 solution Frozen filtered PHM-101 solution was then thawed and ahquoted into vials such that each vial contained 50 Units of PHM-101 activity These Units are as defined heremabove The ahquoted PHM- 101 formulation, to which vanous excipients can be added to protect the enzyme as descnbed elsewhere in the specification, was then frozen and freeze-dned in accordance with standard procedures Analyses conducted dunng the production of freeze-dned PHM-101 were quick in-process analyses, used to control and monitor the effectiveness of the process during each step, as follows The activity (of PHM-101) was assayed throughout the process to check the quantity and functionality of the matenal being produced Activity was measured by momtonng the rate of reaction ith the -nιtroanιlιde ester of succinyl-Ala-Ala-Pro-Phe, a known substrate of chymotrypsin-like enzymes, using a standard assay The protein content was measured at various steps in the process by a standard method known as the Bradford method As enzymes are proteins, this is another means of momtonng the quantity and quality of the matenal being produced by the process Div iding the activ lty number by this yields a useful measure of functionality and purity called the specific activity Protein contaminants or peptide breakdown products of the PHM-101 preparation were tested using standard SDS-poly acrylamide gel electrophoresis Mono-Q FPLC [Pharmacia] is a commercially available analytical chromatography column which separates the components of a mixture by v irtue of their relative charge An aliquot is analyzed v ia the column and eluted protein was detected via ultraviolet adsorption characteristics of the protein Pure molecules show up as a single sharp s mmetπcal peak Other peaks indicate the presence of contaminants (either impurities or breakdown products) Example 5. An embodiment of the present inv ention directed at a method of treatment of corneal w ounds was tested using albino, New Zealand rabbits (2-3 kg), expenmentallv causing alkaline burn wounds of the corneas of anesthetized rabbits followed bv control and inventive treatments, as set forth herein below Forty albino, New Zealand rabbits (2-3 kgs) were anesthetized with intravenous phenobarbital using standard procedures Filter paper discs, 7 mm. were wetted, in the first instance, with 4N sodium hydroxide solution, and were applied to the central part of the cornea for one minute, with precautions taken to avoid involvement of the penpheral part of the cornea, conjunctiva or lids The burned corneas ere then being lrngated with 0 9% sodium chlonde Epithelium was debnded with a cotton tipped applicator, and ciprofloxacin drops (Ocuflex) instilled The animals were randomly divided into two groups and each animal was treated topicallv for 28 davs either with protease PHM-101 (prepared in accordance with Example 4) or a microgel without protease A masked observer performed daily slit lamp biomicroscopy to document the clinical parameters Protease PHM-101 was made up by reconstituting 1 vtal with 2 ml stenle water and adding the solution to 10 ml of microgel prepared with Carbopol® 974P according to the procedure in Example 6 to follow The mixture was shaken to homogenize The dose was 50 mcL of the reconstituted gel four times daily, applied 10 minutes after the antibiotic As mentioned above, one group of animals (the gel-onlv group) was treated with the microgel that did not contain enzyme Treatment was started on the day following the wounding and continued for 28 days, with a penod of observation of 1 week off-treatment in the ev ent of incomplete healing Post-operative treatment for all 40 rabbits included the use of a topical antibiotic (ciprofloxacin) four times daily until the cornea was re-epithehalized in order to prevent secondary bactenal infection of the cornea The rabbits were observed daily by slit lamp biomicroscopy to document certain clinical parameters, including size of residual epithelial defect, degree of stromal ulceration. and, at the end of healing, degree of stromal opacification The size of the epithelial defect remaining was assessed by means of a grid in one ocular of the biomicroscope The degree of ulceration and of stromal opacification (scarring) neovasculansation was assessed on a subjective scale of 0 to 4+ (mild to severe) The observations were masked such that the obser er was not aware of whether a particular rabbit was in the protease or the gel-onlv group On dav 28 all the animals with healed epithelial defects were killed and their corneas harvested for histopathological studies The remaining animals were observed for one week without treatment and were then killed on dav 35 to har est corneas for histopathologv Bv day 28 7/20 of the enzvme treated eves had corneal ulcers whilst 6/18 of the placebo-treated eves had ulcers Bv dav 35 (one dav after termination of treatment) 2/20 of the remaining enzvme-treated corneas were ulcerated and 6/18 of the placebo-treated corneas were ulcerated The study did not contain a no-treatment or sahne-onlv treatment group However the wealth of published literature on this animal model indicates that in the same model using a IN alkali burn (a much less severe burn than the 4N alkali burn used in this Example) approximately 75% of the eyes would develop ulcers This example provides results that demonstrate the benefit of multifunctional protease therapv of alkali burn-induced corneal ulceration, wherein corneal destruction is reduced or avoided This example also demonstrates the benefit of the use of microgel alone which caused a reduction in corneal destruction, though not as markedly as when the microgel was applied in combination with the multifunctional protease Example 6 This example sets forth methods for prepanng hydrogel and microgel used in the context of the present invention The microgel is used by itself or in combination with other agents, such as the knll- denved multifunctional hvdrolases also set forth herein The chemicals and matenals used therefor were Glycerol (Merck, Darmstadt, GERMANY) Carbopol® polyamomc polymers (BFGoodnch Company Specialty Polymers and Chemicals Brecksville OH) dnsopropanol amine (Aldnch), distilled water and 10% sodium hvdroxide The final concentrations of the component chemicals were 23 5% w/v Glvcerol stock (which is 87%) w/vv) 0 8% w/v of the desired polyamomc polymer, and distilled water and the sodium hydroxide (10%) or dnsopropanol amine used to adjust the pH to 7 4 and make to volume Using standard stenle procedures, the carbopol was mixed in small amounts with distilled water under slow agitation with a propeller stiner The stirnng continued until the powder was dissolv ed Anv trapped air was removed bv reducing the pressure (water operated acuum gauge) Glycerol was added under slow stirnng and the pH was measured, and the 10% NaOH solution or the dnsopropanol amine was used to adjust the composition to pH 7 4 Gelation occuned resulting in a clear transparent microgel The resultant microgel was stored at 4°C Using the same methodology but with weight to weight measurements of amounts, the following 10 g batches were made Batch 1 Xanthan gum 0 6 g Keltrol-T brand, supplied by Monsanto, Example 7. The Knll broad-specificity senne protease activity was routinely assayed using Succiny -Ala- Ala-Pro-Phe-/?-nιtroanιhde (Sigma Chemical Co , St Louis, MO) and the following chemicals, materials, and procedures The Assay Buffer is composed of 0 25 M HEPES (5 96 g HEPES/100 ml) and 1 mM CaCl; (100 μl 1 M CaCl; stock solution/100 ml) The solution is prepared by combimng the HEPES and CaCL in about 50 ml distilled water, adjusting the pH to 7 2 with 4 M NaOH and adding more distilled water to 100 ml HEPES changes pH with temperamre by -0 015 pH unit for each degree C Therefore, the pH of the buffer is adjusted at the assay temperature (25°C) The Substrate stock solution is 25 mM Succιnyl-Ala-Ala-Pro-Phe- -mtroanιlιde dissolved in dimethylsulfoxide (DMSO) (156 2 mg/ 10 ml) The substrate does not dissolve well in DMSO that contains water Therefore the DMSO is stored in a container with desiccant Dry DMSO becomes solid at 16-19°C The Enzyme solution is prepared by making dilutions thereof in distilled water If the enzy e is stored on ice or in the refngerator, the enzyme solution is allowed to equilibrate at room temperature for at least 10 minutes pnor to the assay The assay was performed at 25°C in a thermostatted 1 ml polycarbonate cuvette A change in the absorbance at 410 nm was monitored with time The reaction rate in μmoles product formed per minute was calculated from the slope of the curve A410 vs Time (mm) The assay was performed by placing via pipette the following into the cuvette 920 μl Assay Buffer and 60 μl Substrate Stock Solution The Assay Buffer-Substrate Stock Solution was stirred thoroughly back and forth with a cuvette stiner to make sure that the substrate solution was completely mixed with the buffer (turning or swirling the cuvette stiner in the solution was insufficient for thorough mixing) The stiner was allowed to stand in the cuvette, which was placed in a rack in a waterbath at 25°C for at least 3 minutes At the end of the incubation time, the cuvette was dned on the outside with a paper towel and placed in the thermostatted cuvette holder Then 20 μl Enzyme solution was added to the cuvette using a liquid measunng device that delivers 20 μl wtth high accuracy (Hamilton synnge. P20 Gilson pipette, or low volume Rainin automatic pipette was used) All pipettes used were well calibrated a 1 μl enor in volume in this assay can result in a 5% enor in the final result The Enzyme was mixed with the Substrate solution thoroughly with the cuvette stiner (stir back and forth, not turn), the sample chamber was closed and the measurement was started by measunng the absorbance change with time over a 2 minute and 20 second penod giving at least 6 slope readings over 20 seconds each The first 20 seconds of each reaction is the lag time while the slopes of the next six 20 second periods are recorded. The two consecutive readings that give the highest slope in dA/min are chosen to represent the rate of the reaction An average of those two numbers is calculated and multiplied by 5 68 to yield the activity concentration of the solution in U/ml The nucleic acid or amino acid sequences refened to herein by SEQ ID NOs are as follows Example 8 The following example illustrates reduction of surgical adhesions by typical microgel formulations of the present invention Compositions of the present invention were prepared as described in Example 6 These compositions were tested for their ability to inhibit formation of adhesions in the rabbit sidewall model as follows Animals Female New Zealand White rabbits, 2 4-2 7 kg, (Insh Farms.
