Popis: The enzyme Glyceraldehyde-3-Phosphate Dehydrogenase from Schistosoma mansoni (SmGAPDH) is characterized as a therapeutical target for schistosomiasis. In this context, we report here the experimental structure, structural analyses and comparisons of SmGAPDH, the first one from a Platyhelminth. The enzyme was expressed, purified and assayed for crystallization, what allowed the obtainment of crystals of sufficient quality to collect X-ray diffraction data up to 2.51 A resolution. SmGAPDH is the only GAPDH to present the sequence NNR (its residues 114–116) which leads to (especially R116) a hydrogen bond network that possibly reflects on the flexibility of residues to interact with the adenine part of NAD+, speculated to be important for differential drug design.
