ABSTRACT:
The present invention relates to a gene derived from Pseudomonas chlororaphis B23 strain which encodes a polypeptide having nitrile hydratase activity being capable of hydrating nitriles to amides. The invention also relates to a recombinant DNA containing the gene, and a transformant transformed with the recombinant DNA. The present invention further relates to a method of producing nitrile hydratase using the transformant and of amides using nitrile hydratase.
