[a] Experimental conditions: 1 mL final volume in Eppendorf tubes; buffer: ammonium formate (2 m, pH 8.2–9.0); T: 30 °C; reaction time: 24 h; agitation orbital shaker (170 rpm); [substrate]: 20 mm; [NAD+]: 1 mm; [LysEDH or LE‐AmDH variant]: 45 μm; [Cb‐FDH]: 16 μm. NC 1: reaction without LysEDH or LE‐AmDH variant; NC 2: reaction without any enzyme addition (LysEDH or LE‐AmDH, and FDH). In all cases, NC1 and NC2 resulted in no detectable analytical yields for amines or alcohols. [b] The reported yields (%) are obtained from the average values obtained from two independent experiments. [c] Numbers in parentheses indicate the analytical yields (%) of the alcohols formed as by‐products. n.d.: not detected.
