Aminotransferases are widely exploited in simple as well as more elaborate multi-enzymatic cascade reactions as an environmentally friendly alternative to transition metal catalysis. However, efficient selective conversion of numerous targets is a great limitation to date . Attempts to improve substrate scope have been undertaken by generation and screening of large mutant libraries, which is very time-consuming and raises costs concerns . Recent approaches explored the use of molecular docking of demanding substrates, followed by energy minimization and/or MD simulations [1;3]. Still, the best results have been obtained by extensive mutagenesis and screening.
