Fig. 4From: A strategy to identify a ketoreductase that preferentially synthesizes pharmaceutically relevant (S)-alcohols using whole-cell biotransformationBinding mode of substrate moleucles. Molecular docking predicted binding interaction (depicted in dashed black lines) modes for compound 1a, compound 2b, compound 3c, and compound 7d. Substrates are represented with blue sticks, catalytic residues and NADPH are shown as green and yellow sticks respectively. Hydrogen bonds between substrate and triad residues are depicted with broken linesBack to article page
