Interactions of oxalate and NADH in the ternary LDHA complex. (a, b) Solvent-excluded tunnel with oxalate and NADH bound shown in two different views. LDHA is shown in grey space-filling representation with its active-site loop coloured orange. Ligands are shown in stick representation, with oxalate C atoms coloured green, NADH C atoms yellow, N atoms blue, O atoms red and phosphates orange. (c) Interactions between oxalate and the LDHA substrate-binding site. Interacting side chains are shown in stick representation. (d) Interactions between NADH and the co-substrate-binding site. |
