MUTANT FORMATE DEHYDROGENASE, GENE ENCODING SAME, AND METHOD FOR PRODUCING NADH

摘要

Durability of formate dehydrogenase is improved with the use of formate dehydrogenase exhibiting high specific activity that is unpredictable from conventional findings. A specific amino acid substitution is introduced into Gibberella zeae-derived formate dehydrogenase. Mutant formate dehydrogenase exhibits durability that is extremely superior to that of wild-type formate dehydrogenase. Thus, the productivity of NADH that is produced using the mutant formate dehydrogenase can be improved.
