The unfavorable reaction equilibrium of transaminase-catalyzed reactions is a major challenge for the efficient biocatalytic synthesis of chiral amines. In this study the synthetic utilization of a salt-based, continuous in situ-product crystallization is

The synthesis of enantiopure amines via amine transaminases involves several challenges including unfavorable reaction equilibria and product inhibition. Described here is a non-catalytic approach to overcome such problems by using an in situ-product crystallization (ISPC) to selectively remove a targeted product amine from an amine transaminase-catalyzed reaction. The continuous removal of the product amine from its reaction solution as a barely soluble salt effectively yields a displacement of the reaction equilibrium towards the products and facilitates a simple downstream processing approach via filtration. The targeted product amine is eventually obtained from the salt, while the counterion compound can be easily recycled.
