Malate dehydrogenase (decarboxylating) () or NAD-malic enzyme (NAD-ME) is an enzyme that catalyzes the chemical reaction :(S)-malate + NADP+ pyruvate + CO2 + NADPH Thus, the two substrates of this enzyme are (S)-malate and NAD+, whereas its three products are pyruvate, CO2, and NADH. Malate is oxidized to pyruvate and CO2, and NAD+ is reduced to NADH. This enzyme belongs to the family of oxidoreductases, to be specific, those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (S)-malate:NAD+ oxidoreductase (decarboxylating). This enzyme participates in pyruvate metabolism and carbon fixation. NAD-malic enzyme is one of three decarboxylation enzymes used in the inorganic carbon concentrating mechanisms of C4 and CAM plants. The others are NADP-malic enzyme and PEP carboxykinase.〔 〕〔 〕 ==Structural studies== As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Malate dehydrogenase (decarboxylating)」の詳細全文を読む スポンサード リンク
