Superposition of the human LDH-A apo form (grey) and NADH binary complex (purple) reported here with the ternary complex bound to NADH and the competitive inhibitor oxamate (two different monomers shown in blue and light blue, respectively; PDB entry 1i10; Read et al., 2001), highlighting the conformational changes upon cofactor and substrate binding, with key residues shown in stick representation. |
