  • Chondroitinase I and chondroitinase II producing mutants of P. vulgaris
    Patent number: 5888798
    Abstract: Mutant Proteus vulgaris strains are provided that, when grown in the absence of an exogenous chondroitinase I and II inducer, produce P. vulgans chondroitinase I and chondroitinase II proteins. The mutants typically produce chondroitinase I and II proteins in the absence of exogenous inducers and in amounts in excess of those produced by wild-type P. vulgaris strains induced with such inducers. Two classes of such mutants, Classes 1 and 2, are disclosed. Class 1 and class 2 mutants differ in the relative amounts of chondroitinases I and II produced when cells are grown in casamino acids--supplemented minimal medium. Additional phenotypic variants that release chondroitinase I protein into the culture medium are provided as well. Also contemplated is a method for producing P. vulgaris chondroitinase I and II proteins.
