Inactivation of maize NADP-malic enzyme by Cu2+ -ascorbate

open access: yes, 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.

Nicotinamide-adenine dinucleotide-linked "malic" enzyme in flight muscle of the tse-tse fly (Glossina) and other insects.

open access: yes, 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 ...

Characterization of the NADP(+)-dependent malic enzyme of Sinorhizobium (Rhizobium) meliloti and investigations into the requirements of malate uptake and malic enzyme activity in bacteroids

open access: yes, 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 ...

Creation of an allosteric site and a NAD+ binding site in cytosolic NADP+-dependent malic enzyme.

open access: yes, 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 ...
