Candida biodinii Formate Dehydrogenase mutants, gene sequences encoding them and use of these Formate Dehydrogenase mutants

摘要

The invention relates to new mutants of formate dehydrogenase from Candida boidinii, new gene sequences encoding these and use of the new formate dehydrogenases.The wild type FDH used hitherto in the industrial process for preparing amino acids becomes inactive after a certain time. New mutants of this wild type have been produced by targeted mutagenesis of a recombinant FDH from E. coli. The new mutants are preferably used in an enzymatic process for preparing chiral compounds.
