Fig. 1From: Validating the inhibitory effects of d- and l-serine on the enzyme activity of d-3-phosphoglycerate dehydrogenases that are purified from Pseudomonas aeruginosa, Escherichia coli and human colonSequence alignment of PGDH from P. aeruginosa, E. coli, and human. The number denotes the position of the amino acid residue in the sequence of E. coli PGDH from a previous report by Tobey and Grant [23]. The black boxes indicate identical residues, and the gray boxes show amino acid similarity. Blue dots show the Pro-336-Gly-337 at the connecting region between the ACT domain and the substrate-binding domain in P. aeruginosa PGDH [7, 8]. PA refers to P. aeruginosa, EC to E. coli, and HS to humanBack to article page
