A one‐pot deracemization strategy for α‐chiral amines is reported involving an enantioselective deamination to the corresponding ketone followed by a stereoselective amination by enantiocomplementary biocatalysts. Notably, this cascade employing a ω‐transaminase and amine dehydrogenase enabled the access to both (R)‐and (S)‐amine products, just by controlling the directions of the reactions catalyzed

A novel thermostable ω-transaminase from Thermomicrobium roseum which showed broad substrate specificity and high enantioselectivity was identified, expressed and biochemically characterized. The advantage of this enzyme to remove volatile inhibitory by-products was demonstrated by performing asymmetric synthesis and kinetic resolution at high temperature.
