>cd06826 PLPDE_III_AR2 Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme, Alanine Racemase 2. This subfamily is composed of bacterial alanine racemases (EC 5.1.1.1) with similarity to Yersinia pestis and Vibrio cholerae alanine racemase (AR) 2. ARs catalyze the interconversion between L- and D-alanine, an essential component of the peptidoglycan layer of bacterial cell walls. These proteins are similar to other bacterial ARs and are fold type III PLP-dependent enzymes containing contains an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain. They exist as homodimers with active sites that lie at the interface between the TIM barrel domain of one subunit and the beta-sandwich domain of the other subunit. Homodimer formation and the presence of the PLP cofactor are required for catalytic activity.
