Phosphoenolpyruvate carboxykinase and gluconeogenesis in grape pericarp

open access: yesPlant Physiology and Biochemistry, 2015
Glycolysis from sugars is necessary at all stages of development of grape pericarp, and this raises the question as to why gluconeogenesis from malate occurs. Phosphoenolpyruvate carboxykinase (PEPCK) is required for gluconeogenesis in grape pericarp.

Does phosphoenolpyruvate carboxykinase have a role in both amino acid and carbohydrate metabolism?

open access: yesAmino Acids, 2001
Phosphoenolpyruvate carboxykinase (PEPCK) catalyses the reversible decarboxylation of oxaloacetate to yield phosphoenolpyruvate and CO2. The role of the enzyme in gluconeogenesis and anaplerotic reactions in a range of organisms is discussed, along with ...

Inhibition of phosphoenolpyruvate carboxykinase by streptonigrin

Biochemical Pharmacology, 1982
Streptonigrin, an antibiotic with antineoplastic activity, inhibited rat liver phosphoenolpyruvate carboxykinase with an I50 of 0.3 microM when excess FeCl2 was present. No inhibition occurred in the absence of added metal ion. Inhibition was partial and noncompetitive versus ITP and oxalacetic acid.

Stereochemistry of phosphoenolpyruvate carboxylation catalyzed by phosphoenolpyruvate carboxykinase

Biochemistry, 1986
The stereochemistry of the carboxylation of phosphoenolpyruvate to yield oxalacetate, catalyzed by chicken liver phosphoenolpyruvate carboxykinase and by Ascaris muscle phosphoenolpyruvate carboxykinase, was determined. The substrate (Z)-3-fluorophosphoenolpyruvate was used for the stereochemical analysis.

A bioluminescent assay for the determination of phosphoenolpyruvate carboxykinase activity in nanogram-sized tissue samples

open access: yesAnalytical Biochemistry, 1988
A highly specific and sensitive assay for the determination of phosphoenolpyruvate carboxykinase (PEPCK) in nanogram-sized tissue samples is described. This test system is based on the stoichiometric transformation of phosphoenolpyruvate into ATP.

Phosphoenolpyruvate carboxykinase cytosolic and mitochondrial isoforms are expressed and active during hypoxia in the white shrimp Litopenaeus vannamei.

Comparative Biochemistry and Physiology Part B Comparative Biochemistry, 2018
Hypoxic zones in marine environments are spreading around the world affecting the survival of many organisms. Marine animals have several strategies to respond to hypoxia, including the regulation of gluconeogenesis.
