    N-terminal amino acid sequence of mutant strainBrevibacterium sp. adipamidase

    The adipamidase of a mutant strainBrevibacterium sp. R312 involved in the degradation of adiponitrile to adipic acid was purified. Its N-terminal amino acid sequence was shown to be identical toBrevibacterium sp.

    Regulation of nitrile-hydratase synthesis in a Brevibacterium species

    The regulation of nitrile-hydratase biosynthese was studied in Brevibacterium sp R 312. Enzyme biosynthesis was not influenced by any carbon and nitrogen source used in the growth medium. It was, however, repress...
