Abstract

A recombinative D- amino acid oxidase and its DNA code sequence. Activity to catalysis rhzomorphC of the enzyme is 25% higher than that of its parents at least.

Description

This application is a divisional application of the invention patent application with the application number 200410030842.8 submitted by the applicant Bairui Global Co., Ltd. on April 8, 2004. technical field The invention relates to the technical field of bioengineering, in particular to the preparation and application of a new D-amino acid oxidase. The two high-activity recombinant D-amino acid oxidases provided by the invention can be used to convert cephalosporin C (cephalosporin C) into glutaryl-7-aminocephalosporanic acid (glutaryl-7-aminocephalosporanic acid). Background technique The mother nucleus of semi-synthetic cephalosporins, 7-aminocephalosporanic acid (7-aminocephalosporanic acid), can be obtained by chemically cracking cephalosporin C. However, the chemical method uses a large amount of toxic chemical reagents, which pollutes the environment, and the reaction steps are complicated and the yield is low. In recent years, enzymatic method has become another ...
