A regulatory factor involved in expression of nitrilase gene, and its gene

摘要

The invention relates to a regulatory factor substantially containing an amino acid sequence represented by SEQ ID NO:1 and having the action of activating a nitrilase gene promoter, a regulatory factor gene containing DNA coding substantially for said regulatory factor, a recombinant plasmid containing said regulatory factor gene, a nitrilase gene containing a promoter region and a DNA region capable of replicating in a microorganism belonging to the genus Rhodococcus, and a transformant transformed with said recombinant plasmid.;According to the present invention, there are provided a regulatory factor gene containing DNA coding substantially for a regulatory factor having the action of activating a nitrilase gene promoter, a recombinant plasmid containing said regulatory factor gene, and a transformant transformed with said plasmid.
