Fig. 5From: Systematic engineering enables efficient biosynthesis of L-phenylalanine in E. coliĀ from inexpensive aromatic precursorsBiotransformation of phenylpyruvate into L-phenylalanine. a L-phenylalanine production from phenylpyruvate by coexpressing Bacillus badius phenylalanine dehydrogenase (PheDH) and Candida boidinii formate dehydrogenase (FDHV120S). FDH was used for cofactor NADH regeneration. b The tolerance of the key enzymes PheDH and FDHV120S to benzaldehyde. Error bars are the standard deviation for three independent experimentsBack to article page
