Phosphoenolpyruvate Carboxylase of Escherichia coli
Abstract Phosphoenolpyruvate carboxylase was purified from Escherichia coli, strain B (ATCC 11303), and its properties studied. Its amino acid composition and some of its structural properties closely resemble those of the enzyme recently purified by Smith ((1971) J. Biol. Chem. 246, 4234–4241).

Escherichia coli Phosphoenolpyruvate Carboxylase [PDF]
Abstract Phosphoenolpyruvate carboxylase of Escherichia coli was purified to homogeneity. The molecular weight of the native protein, as determined by sedimentation equilibrium analyses, is 402,000. Sedimentation equilibrium analyses on the enzyme denatured in 3.5 m, 5 m, and 7 m guanidine hydrochloride gave a single species with a molecular weight of ...

Background Organic acid secretion is a widespread physiological response of plants to alkalinity. However, the characteristics and underlying mechanism of the alkali-induced secretion of organic acids are poorly understood.

Apicomplexan parasites predominantly generate ATP and lactic acid through glycolysis and anaerobic glucose metabolism, incorporating CO2 into glycolysis via a stage-dependent phosphoenolpyruvate carboxylase (PEPC) mechanism.

Enhanced tolerance to drought in transgenic rice plants overexpressing C4 photosynthesis enzymes
Maize-specific pyruvate orthophosphate dikinase (PPDK) was overexpressed in rice independently or in combination with the maize C4-specific phosphoenolpyruvate carboxylase (PCK). The wild-type (WT) cultivar Kitaake and transgenic plants were evaluated in

Kochia sieversiana (Pall.) C.A. Mey. is a forage plant that can grow in extremely alkalinized grasslands at pH 10 or higher. Accumulation of a large amount of oxalic acid (OxA) is a primary characteristic of K. sieversiana.

Light Modulation of Maize Leaf Phosphoenolpyruvate Carboxylase [PDF]
Phosphoenolpyruvate carboxylase (PEPC) was extracted from maize (Zea mays L. cv Golden Cross Bantam T51) leaves harvested in the dark or light and was partially purified by (NH(4))(2)SO(4) fractionation and gel filtration to yield preparations that were 80% homogeneous.

Multiple conformations in solution of the maize C4-phosphoenolpyruvate carboxylase isozyme
The photosynthetic phosphoenolpyruvate carboxylase isozyme from C4 plants (PEPC-C4) has a complex allosteric regulation, involving positive cooperativity in binding the substrate phosphoenolpyruvate as well as positive and negative allosteric effectors ...

Glycolytic pyruvate kinase moonlighting activities in DNA replication initiation and elongation [PDF]
Cells have evolved a metabolic control of DNA replication to respond to a wide range of nutritional conditions. Accumulating data suggest that this poorly understood control depends, at least in part, on Central Carbon Metabolism (CCM). In Bacillus subtilis , the glycolytic pyruvate kinase (PykA) is intricately linked to replication.
