Abstract: The invention is directed to polypeptides having epoxide hydrolase activity, polynucleotides encoding the polypeptides, antibodies that bind to these polypeptides, and methods for making and using these polynucleotides and polypeptides. The epoxide hydrolases are used to catalyze the hydrolysis of epoxides and arene oxides to their corresponding diols.

Abstract: The present invention relates to recombinant DNA which encodes the AsiSI restriction endonuclease as well as AsiSI methylase, expression of AsiSI restriction endonuclease and AsiSI methylase in E. coli cells containing the recombinant DNA.

Abstract: A genomic DNA library of Thermus filiformis was constructed using pBR322 as a cloning vector. The methylase selection method was used to clone the TfiI methylase gene (tfiIM). A clone carrying an active TfiI methylase was identified. After sequencing the complete TfiI methylase gene and its downstream DNA sequence, a recombinase homolog was found. Because the methylase and its cognate endonuclease gene are located in proximity to each other in a particular restriction-modification system, efforts were made to clone the upstream DNA by inverse PCR. After two rounds of inverse PCR, one open reading frame (ORF1) was found upstream of the TfiI methylase gene. This ORF1, containing a Shine-Dalgarno sequence and a TATA box on the upstream side, was cloned and expressed, and TfiI endonuclease activity was detected in crude cell extracts. It is concluded that ORF1 encodes TfiI restriction endonuclease.

Abstract: The present invention relates to a modified cellulase protein which is advantageously used in the treatment of textiles. Particularly, a method for treating a cellulose containing fabric is provided comprising the steps of forming an aqueous solution comprising a cellulase composition which differs from a precursor cellulase in that it has been enlarged and contacting the aqueous solution with a cellulose containing fabric for a time and under conditions appropriate to treat the fabric. The enlarged cellulase may comprise a multimeric composition of two or more distinct cellulase units or a single cellulase which has had adhered thereto polymeric or fibrous constituents.

Abstract: A method for screening or detection of a non-enzyme catalytic polypeptide or protein for the conversion of a substrate S to a product P is provided, in which a preparation containing the potential catalyst is contacted with the substrate S immobilized to a support and the immobilized product P obtained is detected, preferably by immunoassay. The method is preferably used for the screening of hybridoma supernatants for catalytic monoclonal antibodies that catalyze acyl transfer reactions, e.g., hydrolysis or aminolysis, condensation reactions and resolution of enantiomers.

Abstract: The present invention provides purified and isolated polynucleotide sequences encoding the novel G protein-coupled receptor kinase designated GRK6. Also provided by the invention are methods and materials for the recombinant production of GRK6 enzyme and methods for identifying compounds which modulate the protein kinase activity of GRK6.

Abstract: Described are methods and means for the construction of strains of yeast capable of producing cellulolytic enzymes. This is achieved by the transfer of chromosomal genes or cDNA copies of mRNAs coding for cellulolytic enzymes isolated from the fungus Trichoderma reesei to yeast cells using recombinant DNA vectors capable of replicating in yeast. The correct expression of these cellulolytic genes in yeast leads to the production of cellulolytic enzymes which are secreted from the cell. This allows the yeast to hydrolyze 3-1,4-glucan substrates such as cellulose.

Abstract: The invention relates to yeast leukotriene A.sub.4 hydrolase enzymes and nucleic acids.

Abstract: A novel superoxide dismutase prepared from a superoxide dismutase-producing strain of the genus Nocardiopsis. The enzyme is a tetramer with a molecular weight of about 8.8.times.10.sup.4, composed of sub-units of about 2.2.times.10.sup.4. The superoxide dismutase contains 1.56 g-atoms of iron per mole but no copper or manganese. Potassium cyanide at a concentration of 1 mM does not inhibit activity, however exponential inactivation is caused by 5 mM hydrogen peroxide.
