The enzymatic reaction of HILDH and 4-HIL stereoisomers production. (a) Schematic diagram of the enzymatic reaction of HILDH. HILDH reduces AMKP to 4-HIL in an NADH-dependent manner. Asymmetric centers are shown in asterisks. (b) HPLC chromatogram of 4-HIL stereoisomers produced (left) and their production ratios (right). The reaction mixtures were derivatized with GITC and detected by HPLC. Each peak label on the chromatogram (left) corresponds to each 4-HIL stereoisomer listed on the right. “No enzyme” indicates the reaction mixtures without HILDH.
