Fig. 1From: Active-site engineering of ω-transaminase from Ochrobactrum anthropi for preparation of L-2-aminobutyric acidModel of α-ketobutyric acid docking into the active site of OATA. pyridoxamine 5′-phosphate (PMP) and α-ketobutyric acid are shown in thick sticks. The hydrogen bonds and Pi-Alkyl interactions are indicated with green and pink dotted lines, respectively. The Cα − NPMP and Oβ − NK287 distances are designated by dark green and purple lines, respectivelyBack to article page
