Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) is the carboxylic acid derived from the enol of pyruvate and phosphate. It exists as an anion. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in organisms, and is involved in glycolysis and gluconeogenesis.
Pyruvate kinase is the enzyme involved in the last step of glycolysis.It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP. [1]
Thus, the two substrates of this enzyme are phosphoenolpyruvate and glycerone, whereas its two products are pyruvate and glycerone phosphate. This enzyme belongs to the family of transferases , specifically those transferring phosphorus-containing groups ( phosphotransferases ) with an alcohol group as acceptor.
The systematic name of this enzyme class is phosphoenolpyruvate:protein-L-histidine Npi-phosphotransferase. Other names in common use include phosphoenolpyruvate sugar phosphotransferase enzyme I, phosphopyruvate-protein factor phosphotransferase, phosphopyruvate-protein phosphotransferase, sugar-PEP phosphotransferase enzyme I, and phosphoenolpyruvate:protein-L-histidine N-pros ...
In enzymology, a phosphoenolpyruvate mutase (EC 5.4.2.9) is an enzyme that catalyzes the chemical reaction. phosphoenolpyruvate 3-phosphonopyruvate. Hence, this enzyme has one substrate, phosphoenolpyruvate (PEP), and one product, 3-phosphonopyruvate (PPR), which are structural isomers.
The 3 substrates of this enzyme are ATP, pyruvate, and H 2 O, whereas its 3 products are AMP, phosphoenolpyruvate, and phosphate. This reaction catalyzed by pyruvate, water dikinase can run in both directions, but has a strong preference for AMP, phosphate, and phosphoenolpyruvate as substrate and typically runs in the ATP producing direction ...
The phosphoryl group on PEP is eventually transferred to the imported sugar via several proteins. The phosphoryl group is transferred to the Enzyme E I (EI), Histidine Protein (HPr, Heat-stable Protein) and Enzyme E II (EII) to a conserved histidine residue, whereas in the Enzyme E II B (EIIB) the phosphoryl group is usually transferred to a cysteine residue and rarely to a histidine.
The three states of pyruvate, phosphate dikinase (unphosphorylated, monophosphorylated, and diphosphorylated) as it converts pyruvate to phosphoenolpyruvate (PEP). P i = phosphate group. E-His = histidine residue of the enzyme. Pyruvate, phosphate dikinase, or PPDK (EC 2.7.9.1) is an enzyme in the family of transferases that catalyzes the ...
