Conversion [%] of 1 a (50 mm) in the presence of lyophilised whole cells of E. coli BL21(DE3) expressing Fus‐SMO (5 mg mL⁻¹) and E. coli JM101 expressing pSPZ10 (StyA/StyB, 5 mg mL⁻¹). Reactions were carried out in glass vials introduced into a sealed pressurised chamber (Figure S5). The biotransformations were performed in a biphasic system [KPi (pH 8, 50 mm)/ n‐heptane (1:1, v/v, 1 mL total reaction volume)] containing NAD⁺ (1 mm), FAD (50 μm), HCOONa (250 mm, 5 equiv.) and Cb‐FDH (10 μm). Catalase (2 μm) was added in selected experiments. The mixtures were incubated at 30 °C, 200 rpm for 20 min. Two independent experiments were carried out, both in duplicate. Error bars represent the standard deviation.
