Revisiting D-Acylases for D-Amino Acid Production.

ABSTRACT: N-Acyl-D-amino acid deacylases (EC 3.5.1.81, also known as D-acylases) have been studied for decades for their utility in the kinetic resolution of N-acetyl-D,L-amino acids (NAAs) due to a marked stereospecificity. In conjunction with an N-succinyl-amino acid racemase (NSAR), they impulse the dynamic kinetic resolution (DKR) of different NAAs until the corresponding enantiomerically pure D-amino acids. Besides the clear interest in this enzyme cascade, the application of D-acylase/NSAR tandems has been only briefly described outside the industrial field. In this work, we revisit D-acylases for the DKR of NAAs, reporting the characterisation of two new recombinant D-acylases belonging to Bordetella petrii and Klebsiella pneumoniae. The enzymes were successfully coupled with the recombinant
