Abstract
The present invention has disclosed the amino acid sequence and nucleotide sequence of the .alpha.- and .beta.-subunits of two types of nitrile hydratase derived from Rhodococcus rhodochrous J-1. The DNA fragment encoding nitrile hydratase is inserted into an expression vector and the recombinant vector is used for transformation. The transformant contains multiple copies of the gene and can produce much higher level of nitrile hydratase compared with conventionally used microorganisms.
