1.1.1.251 | modeling of structure and docking analysis of substrate, Zn2+ and NAD+. Cys 37, His 58, Glu 59, Glu 142 residues form an active site pocket similar to known GPDH. A catalytic Zn2+-binding domain and a cofactor NAD+-binding domain with strong hydrogen bonding contacts with the substrate and the cofactor are identified |
