although both types of enzymes, NAD-dependent D- and L-lactate dehydrogenases (D-LDH, EC 1.1.1.28; and L-LDH, EC 1.1.1.27) catalyze identical reactions except for the distinct chirality of the lactate product, they are evolutionarily distinct from each other.

comparison of the apo and ternary complex structures of Fusobacterium nucleatum FnLDH and Escherichia coli EcLDH and Pseudomonas aeruginosa PaLDH. FnLDH and EcLDH exhibit positive cooperativity in substrate binding, and PaLDH shows negatively cooperative substrate binding. The three enzymes consistently form homotetrameric structures with three symmetric axes, the P-, Q-, and R-axes, which allows apo-FnLDH and EcLDH to form wide intersubunit contact surfaces between the opened catalytic domains of the two Q-axis-related subunits in coordination with their asymmetric and distorted quaternary structures. apo-PaLDH possesses a highly symmetrical quaternary structure and partially closed catalytic domains that are favorable for initial substrate binding and forms virtually no intersubunit contact surface between the catalytic domains
