    摘要: This invention provides DNA fragments for efficiently preparing a protein having asymmetric hydrolase activity for 4-substituted 1,4-dihydropyridine derivatives, transformants obtained by using such a DNA fragment, and a process for preparing the aforesaid enzyme. Specifically, an isolated gene derived from the chromosome of Streptomyces viridosporus and encoding a protein having asymmetric hydrolase activity for 4-substituted 1,4-dihydropyridine derivatives, plasmids having the aforesaid gene integrated thereinto, transformants obtained by using such a plasmid, and a process for preparing the aforesaid enzyme by using such a transformant are disclosed. A process for the enzymatic conversion of 4-substituted 1,4-dihydropyridine derivatives by using the aforesaid enzyme is also disclosed.
