two distinct active site LDH/NADH-oxamate complex conformations, a major populated structure wherein all significant hydrogen-bonding patterns are formed at the active site between protein and bound ligand necessary for the catalytically productive Michaelis complex and, a minor structure in a configuration of the active site that is unfavorable to carry out catalyzed chemistry. This latter structure likely simulates a dead-end complex in the reaction mixture. The evolution of the encounter complex between LDH/NADH and oxamate collapses via a branched reaction pathway to form the major and minor bound species. Once the encounter complex is formed between LDH/NADH and substrate, the ternary protein-ligand complex appears to fold to form a compact productive complex in an all or nothing like fashion with all the important molecular interactions coming together at the same time
