The present invention relates to a novel glucose-6-phosphate dehydrogenase (hereinafter referred to as “G6PD”) derived from a bacterium belonging to the genus Corynebacterium, a DNA encoding the enzyme, a recombinant DNA comprising the DNA, a transformant comprising the recombinant DNA, a transformant comprising the DNA on its chromosome, and a process for producing L-amino acid or G6PD which comprises culturing the transformant.According to the present invention, a modified G6PD and a DNA encoding the G6PD are obtained, and the productivity of L-amino acid by a microorganism can be improved by using the modified G6PD.
摘要:
Provided is an efficient process for producing L-glutamine or L-glutamic acid using a microorganism. L-glutamine or L-glutamic acid is produced by culturing in a medium a microorganism in which has an ability to produce L-glutamine or L-glutamic acid, and in which an ability to form a superhelical double-stranded DNA is decreased compared with that of the parent strain, producing and accumulating L-glutamine or L-glutamic acid in the medium, and recovering L-glutamine or L-glutamic acid from the medium.
摘要:
