Enzymatic synthesis of carnosine derivatives catalysed by Burkholderia cepacia lipase

Abstract

A new enzymatic synthesis of α,β-dipeptides has been developed with particular focus on the preparation of carnosine (β-alanyl-α-histidine) and analogues. The lipase PS-D from Burkholderia cepacia has been used as a catalyst for the formation of the peptide bond starting from a β-lactam and a protected α-amino acid.
