ABSTRACT:
A method for the production of an enzyme, which comprises culturing in a medium a strain that belongs to a bacterium classified intoCytophagalesorActinomycetes, or a new bacteriumChryseobacteriumsp. No. 9670 belonging to the genusChryseobacterium, and has the ability to produce an enzyme having a property to deamidate amido groups in protein, thereby effecting production of the enzyme, and subsequently collecting the enzyme from the culture mixture and a method for the modification of protein making use of a novel enzyme which directly acts upon amido groups in protein, as well as a gene which encodes the enzyme, a recombinant vector which contains the gene, a transformant transformed with the vector and a method in which the transformant is cultured in a medium to effect production of the protein-deamidating enzyme and then the protein-deamidating enzyme is collected from the culture mixture.
