In this study, we successfully synthesized enantiomerically pure (R)- and (S)-γ-amino acids (>99% ee) using Ï-transaminase (Ï-TA) through kinetic resolution and asymmetric synthesis respectively. The present study demonstrates the high potentiality of Ï-TA reaction for the production of chiral γ-amino acids.

A recyclable glutamate amine donor system employing transaminase (TA), glutamate dehydrogenase (GluDH) and mutant formate dehydrogenase (FDHm) was developed, wherein amine donor Glu was regenerated using GluDH and thereby circumvented the inhibition of TA by α‐ketoglutarate. Various enantiopure β‐, γ‐aminoacids, and amines were successfully synthesized with high conversions and excellent enantiomeric
