Lactate/malate dehydrogenase, N-terminal <p>L-lactate dehydrogenases are metabolic enzymes which catalyse the conversion of L-lactate to pyruvate, the last step in anaerobic glycolysis [<cite idref="PUB00025866"/>]. L-lactate dehydrogenase is also found as a lens crystallin in bird and crocodile eyes. L-2-hydroxyisocaproate dehydrogenases are also members of the family. Malate dehydrogenases catalyse the interconversion of malate to oxaloacetate [<cite idref="PUB00027386"/>]. The enzyme participates in the citric acid cycle.</p><p> This entry represents the N-terminal, and is thought to be a Rossmann NAD-binding fold.</p>
