| BACKGROUND: NAD-dependent glycerol-3-phosphate dehydrogenase (GPDH) catalyzes the interconversion of dihydroxyacetone phosphate and L-glycerol-3-phosphate. Although the enzyme has been characterized and cloned from a number of sources, until now no three-dimensional structure has been determined for this enzyme. Although the utility of this enzyme as a drug target against Leishmania mexicana is yet to be established, the critical role played by GPDH in the long slender bloodstream form of the related kinetoplastid Trypanosoma brucei makes it a viable drug target against sleeping sickness. RESULTS: The 1.75 A crystal structure of apo GPDH from L. mexicana was determined by multiwavelength anomalous diffraction (MAD) techniques, and used to solve the 2.8 A holo structure in complex with NADH. Each 39 kDa subunit of the dimeric enzyme contains a 189-residue N-terminal NAD-binding domain and a 156-residue C-terminal substrate-binding domain. Significant parts of both domains share structural similarity with plant acetohydroxyacid isomeroreductase. The discovery of extra, fatty-acid like, density buried inside the C-terminal domain indicates a possible post-translational modification with an associated biological function. CONCLUSIONS: The crystal structure of GPDH from L. mexicana is the first structure of this enzyme from any source and, in view of the sequence identity of 63%, serves as a valid model for the T. brucei enzyme. The differences between the human and trypanosomal enzymes are extensive, with only 29% sequence identity between the parasite and host enzyme, and support the feasibility of exploiting the NADH-binding site to develop selective inhibitors against trypanosomal GPDH. The structure also offers a plausible explanation for the observed inhibition of the T. brucei enzyme by melarsen oxide, the active form of the trypanocidal drugs melarsoprol and cymelarsan.
