>cd06812 PLPDE_III_DSD_D-TA_like_1 Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzymes Similar to D-Serine Dehydratase and D-Threonine Aldolase, Unknown Group 1. This subfamily is composed of uncharacterized bacterial proteins with similarity to eukaryotic D-serine dehydratases (DSD) and D-threonine aldolases (D-TA). DSD catalyzes the dehydration of D-serine to aminoacrylate, which is rapidly hydrolyzed to pyruvate and ammonia. D-TA reversibly catalyzes the aldol cleavage of D-threonine into glycine and acetaldehyde, and the synthesis of D-threonine from glycine and acetaldehyde. DSD and D-TA are fold type III PLP-dependent enzymes, similar to bacterial alanine racemase (AR), which contains an N-terminal PLP-binding TIM barrel domain and a C-terminal beta-sandwich domain. AR exists 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. Based on their similarity to AR, it is possible mem
