, 2015 In 27 C4 grasses grown under adequate or deficient nitrogen (N) supplies, N-use efficiency at the photosynthetic (assimilation rate per unit leaf N) and whole-plant (dry mass per total leaf N) level was greater in NADP-malic enzyme (ME) than NAD-ME ...

Genetic regulation of malic enzyme activity in the mouse.
, 1991 Cytosolic malic enzyme catalyzes the NADP(+)-dependent oxidative decarboxylation of malate to pyruvate and CO2. Additionally, this enzyme produces large amounts of reducing equivalents (NADPH) required for de novo fatty acid synthesis and provides a ...

Inactivation of maize NADP-malic enzyme by Cu2+ -ascorbate
, 2002 55-59Maize malic enzyme was rapidly inactivated by micromolar concentrations of cupric nitrate in the presence of ascorbate at pH, 5.0. Ascorbate or Cu2+ alone had no effect on enzyme activity.

, 1976 1.. A high activity of NAD-linked "malic" enzyme was found in homogenates of flight muscle of different species of tse-tse fly (Glossina). The activity was the same as, or higher than, that of malate dehydrogenase and more than 20-fold that of NADP ...

Creation of an allosteric site and a NAD+ binding site in cytosolic NADP+-dependent malic enzyme.
, 2014 人類細胞質蘋果酸酶 (c-NADP-ME) 在有二價金屬離子 (如錳、鎂離子) 的存在下，能將蘋果酸及 NADP+催化形成丙酮酸、二氧化碳及NADPH，進行可逆的氧化脫羧反應。人類細胞質蘋果酸酶在結構上是由四個完全相同的單體組合而成的四聚體，可分為結合較緊密的雙聚體界面和較鬆散的四聚體界面，每個單體都具有各自的活化中心。不同於c-NADP-ME，人類粒線體蘋果酸酶 (c-NAD-ME)在雙聚體界面處有一異位調節區，可與反丁烯二酸結合，促使活性提升；而腺苷三磷酸則會和輔因子競爭結合到活化中心，抑制活性 ...

, 2000 Malic enzymes are responsible for the conversion of malate to pyruvate with the concomitant reduction of a nicotinamide cofactor. Previous experiments revealed that Sinorhizobium ( Rhizobium ) meliloti has both a diphosphopyridine (NAD + ) dependent ...

RAT-BRAIN MALIC ENZYME - CHARACTERIZATION AND SUBCELLULAR-DISTRIBUTION
, 1987 Mitochondrial and cytosolic variants of malic enzyme (EC 1.1.1.40 L-malate: NADP+ oxidoreductase, decarboxylating) occur in mammalian tissues. This study concerns characterization of these isoenzymes in rat brain.
