Presence and characteristics of nadp-malic enzyme in soybean nodule bacteroids

Soil Science and Plant Nutrition, 1989
The localization and characteristics of NADP-malic enzyme [EC 1.1.1.40], a key enzyme for succinate oxidation in nodule bacteroids, were surveyed in soybean nodules and bacteroids. Protoplasts prepared from nodules were separated into cortex cell, infected cell, and uninfected cell groups following the determination of NADP-malic enzyme activity in ...

NADP-malic enzyme isoforms in maize leaves.

Biochemistry and molecular biology international, 1996
Two isoforms of NADP-malic enzyme have been characterized in maize leaves. The 72 kDa-form of the protein, present mainly in etiolated maize leaves, has lower specific activity than the 62 kDa-form, which is implicated in C4 metabolism and predominates in green leaves.

Comparative studies of NADP-malic enzyme from C4- and C3-plants

Biochemical and Biophysical Research Communications, 1974
Abstract Some enzymological properties were studied comparatively for NADP-malic enzyme from various C 4 - and C 3 -plants. The enzyme from C 4 -plants of “malate formers” showed relatively low Km(Mal) values (0.10 – 0.25 mM) and high pH optima (more than pH 7.4 – 7.8).

Analogues of NADP+ as inhibitors and coenzymes for NADP+ malic enzyme from maize leaves

Photosynthesis Research, 1991
Structural analogues of the NADP(+) were studied as potential coenzymes and inhibitors for NADP(+) dependent malic enzyme from Zea mays L. leaves. Results showed that 1, N(6)-etheno-nicotinamide adenine dinucleotide phosphate (∈ NADP(+)), 3-acetylpyridine-adenine dinucleotide phosphate (APADP(+)), nicotinamide-hypoxanthine dinucleotide phosphate (NHDP(+

A comparative study of the NADP-malic enzymes from Drosophila and chick liver

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1980
Abstract 1. 1. NADP-Malic enzyme (NADP-ME; l -malate:NADP + oxidoreductase (decarboxylating) EC 1.1.1.40) from Drosophila melanogaster has a mol wt of 266,000 and a subunit mol wt of 67,250 ± 3080. The amino acid composition of Drosophila NADP-ME is closely related to the NADP-ME's from pigeon liver, chick liver, rat liver and E.

Study of the Structure Function Relationship in Maize NADP—Malic Enzyme

2008
NADP-malic enzyme catalyses the reversible oxidative decarboxylation of l-malate to yield carbon dioxide and pyruvate with the concomitant reduction of NADP. Maize presents at least three isoforms of this enzyme, and the “photosynthetic isoform” is responsible for providing CO2 to the Calvin Cycle for carbon fixation. In this work, different aspects of

Presence of essential histidine residues in nadp-malic enzyme from maize

Phytochemistry, 1987
Abstract Modification of maize leaf NADP-malic enzyme by diethylpyrocarbonate (DEP) caused rapid and complete inactivation of the enzyme. The inactivation followed pseudo-first-order reaction kinetics. The inactivation of the enzyme showed saturation kinetics with a half inactivation time, at saturating DEP, equal to 0.15 min and KDEP = 20 mM.

A study on the inactivation of maize leaves nadp-malic enzyme by 3-bromopyruvate

Phytochemistry, 1992
Abstract Bromopyruvate is a noncompetitive inhibitor of maize leaf NADP + -malic enzyme with respect to l -Malate ( K i 1 mM at pH 8.0). Relatively low concentrations of this compound completely and irreversibly inactivated the enzyme. The inactivation followed pseudo-first-order kinetics.

NADP-malic enzyme from maize leaves: a fluorescence study.

Biochemistry and molecular biology international, 1996
NADP-malic enzyme from maize leaves is covalently labeled with a fluorescent-SH reactive probe eosin-5-maleimide (EMA), which reacts with groups that are totally protected by NADP against inactivation. The comparison of the emission fluorescence spectra of the native and the modified enzyme suggests the proximity of the fluorescent groups of the native
