Thermostable glutamate dehydrogenase and process for producing the same

摘要

The present invention provides a process for mass producing recombinant, thermostable GLDH at a low cost. The invention also provides a process for mass producing recombinant, thermostable GLDH at a low cost, by culturing a transformant without using a drug such as IPTG. The invention further provides thermostable GLDH which can use more stable NADH as a coenzyme in an ammonia assay reagent.
