Analytical biotransformation of glycine and aldehydes 1a–i to α-keto acids 4a–i with E. coli OA02. Reactions were performed in duplicate with resting cells E. coli (OA02) (10 g dcw l−1) and 1a–i (10 mM) in KP buffer (50 mM, pH 8.0, 100 µM PLP, and 10% DMSO) at 200 rpm and 25 °C for 24 h. The values are averages of two experiments
