>cd05294 LDH-like_MDH_nadp A lactate dehydrogenases-like structure with malate dehydrogenase enzymatic activity. The LDH-like MDH proteins have a lactate dehyhydrogenase-like (LDH-like) structure and malate dehydrogenase (MDH) enzymatic activity. This subgroup is composed of some archaeal LDH-like MDHs that prefer NADP(H) rather than NAD(H) as a cofactor. One member, MJ0490 from Methanococcus jannaschii, has been observed to form dimers and tetramers during crystalization, although it is believed to exist primarilly as a tetramer in solution. In addition to its MDH activity, MJ0490 also possesses fructose-1,6-bisphosphate-activated LDH activity. Members of this subgroup have a higher sequence similarity to LDHs than to other MDHs. LDH catalyzes the last step of glycolysis in which pyruvate is converted to L-lactate. MDH is one of the key enzymes in the citric acid cycle, facilitating both the conversion of malate to oxaloacetate and replenishing levels of oxalacetate by reductive carbox
