Abstract Amino acids are organic compounds that serve as the building blocks of proteins and peptides. Additionally, they function as bioactive molecules that play important roles in metabolic regulation and signal transduction. The ability of cells to sense fluctuations in intracellular and extrace...

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 t...
