Dramatic difference in the responses of phosphoenolpyruvate carboxylase to temperature in leaves of C₃ and C₄ plants [PDF]

, 2003
Temperature caused phenomenal modulation of phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31) in leaf discs of Amaranthus hypochondriacus (NAD-ME type C4 species), compared to the pattern in Pisum sativum (a C3 plant).

Phosphoenolpyruvate Carboxylase from the Cyanobacterium Synechocystis sp. PCC 6803 is under Global Metabolic Control by PII Signaling.

Molecular Microbiology, 2020
Phosphoenolpyruvate carboxylase (PEPC) is the second major carbon-fixing enzyme in photoautotrophic organisms. PEPC is required for the synthesis of amino acids of the glutamate and aspartate family by replenishing the TCA cycle.

Functional Analysis of the Phosphoenolpyruvate Carboxylase on the Lipid Accumulation of Peanut (Arachis hypogaea L.) Seeds

Journal of Integrative Agriculture, 2013
Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) catalyses phosphoenolpyruvate (PEP) to yield oxaloacetate, which is involved in protein biosynthesis.

Nitrogen metabolism-related enzymes in Mesembryanthemum crystallinum after Botrytis cinerea infection

Biologia Plantarum, 2018
We compared C3 and CAM (crassulacean acid metabolism) states in Mesembryanthemum crystallinum, a facultative CAM species, with respect to the involvement of phosphoenolpyruvate carboxylase (PEPC) and nitrogen metabolismrelated enzymes in plant response ...

New Insights into the Biosynthesis of Succinic Acid by Actinobacillus succinogenes with the Help of Its Engineered Strains

Fermentation, 2023
Succinic acid (SA), a C4 tricarboxylic acid cycle intermediate, is used as raw material for bulk chemicals and specialty chemicals, such as tetrahydrofuran and 1,4-butanediol, as well as also being used to synthesize the biodegradable biopolymers PBS ...

Oxygen Requirement and Inhibition of C4 Photosynthesis . An Analysis of C4 Plants Deficient in the C3 and C4 Cycles [PDF]

, 1998
The basis for O2 sensitivity of C4 photosynthesis was evaluated using a C4-cycle-limited mutant of Amaranthus edulis (a phosphoenolpyruvate carboxylase-deficient mutant), and a C3-cycle-limited transformant of Flaveria bidentis (an antisense ribulose-1,5-

New insights into the mechanisms of plant isotope fractionation from combined analysis of intramolecular 13C and deuterium abundances in Pinus nigra tree‐ring glucose

New Phytologist, Volume 245, Issue 3, Page 1000-1017, February 2025.
Summary Understanding isotope fractionation mechanisms is fundamental for analyses of plant ecophysiology and paleoclimate based on tree‐ring isotope data. To gain new insights into isotope fractionation, we analysed intramolecular 13C discrimination in tree‐ring glucose (Δi′, i = C‐1 to C‐6) and metabolic deuterium fractionation at H1 and H2 (εmet ...

Plausible phosphoenolpyruvate binding site revealed by 2.6 Å structure of Mn2+-bound phosphoenolpyruvate carboxylase from Escherichia coli11The coordinates and structure factors have been deposited in the Protein Data Bank (accession number 1QB4). [PDF]

We have determined the crystal structure of Mn2+-bound Escherichia coli phosphoenolpyruvate carboxylase (PEPC) using X-ray diffraction at 2.6 Å resolution, and specified the location of enzyme-bound Mn2+, which is essential for catalytic activity.
