High-resolution crystal structure of Streptococcus agalactiae glyceraldehyde-3-phosphate dehydrogenase.

ABSTRACT: Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a multifunctional enzyme that plays critical roles in bacterial pathogenesis in some pathogenic bacteria. In this study, the crystal structure of group B streptococcus GAPDH was determined at 1.36?Å resolution. The structure contained an asymmetric mixed holo tetramer, with two NAD ligands bound to two protomers. Further structural analysis identified interesting phosphate ion-binding sites, which shed light on its catalytic mechanism.
