Homo sapiens L-alpha-glycerol-3-phosphate dehydrogenase 1 (GPD1) catalyzes the reversible biological conversion of dihydroxyacetone (DHAP) to glycerol-3-phosphate. The GPD1 protein was expressed in Escherichia coli, and purified as a fusion protein with glutathione S-transferase. Here we report the apoenzyme structure of GPD1 determined by multiwavelength anomalous diffraction phasing, and other complex structures with small molecules (NAD+ and DHAP) by the molecular replacement method. This enzyme structure is organized into two distinct domains, the N-terminal eight-stranded beta-sheet sandwich domain and the C-terminal helical substrate-binding domain. An electrophilic catalytic mechanism by the epsilon-NH3+ group of Lys204 is proposed on the basis of the structural analyses. In addition, the inhibitory effects of zinc and sulfate on GPDHs are assayed and discussed.
