Alanine Racemase (ALR) is a unique bacterial enzyme that racemises L-alanine to D-alanine in bacteria and plays a crucial role in the biosynthesis of bacterial peptidoglycan. In this paper, the structure, function and application of alanine racemase are described to provide a theoretical basis for the in-depth study of bacterial alanine metabolism and the development of related enzyme inhibitors.
