In this study, ten ω-transaminases (ω-TAs) have been investigated to efficiently catalyze the synthesis of twenty-four functionalized benzylamines and pyridylmethylamines. We optimized the reactions, screened suitable amino donors and compared ω-transaminases activities for all aromatic aldehyde substrates. Under the optimized conditions, eighteen aromatic amines have been obtained with 60.4%–96.6% conversions and isolated only via simple extraction and recrystallization with 18.5%–81% yields on a preparative scale. Furthermore, we first immobilized the Bm-STA onto the MOFs via the physical adsorption to overcome the limitation of free enzyme and improve their industrial applications. The obtained Bm-STA/UiO-66-NH2 composites exhibited not only high enzymes loading (80.4 mg g?1) and enzyme activity recovery (95.8%), but also the better reusability, storage stability, pH stability and the tolerance to acetone and DMF.
