Metabolite Identification
Common NamePhosphoenolpyruvic acid
DescriptionPhosphoenolpyruvic acid, also known as PEP or 2-phosphonooxyprop-2-enoate, belongs to the class of organic compounds known as phosphate esters. These are organic compounds containing phosphoric acid ester functional group, with the general structure R1P(=O)(R2)OR3. R1,R2 = O,N, or halogen atom; R3 = organyl group. Phosphoenolpyruvic acid is possibly soluble (in water) and an extremely strong acidic compound (based on its pKa). Phosphoenolpyruvic acid exists in all living species, ranging from bacteria to humans.

4. Alpha-enolase
General function:
Carbohydrate transport and metabolism
Specific function:
Glycolytic enzyme the catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate (By similarity). In addition to glycolysis, involved in various processes such as growth control, hypoxia tolerance and allergic responses (PubMed:7499243). May also function in the intravascular and pericellular fibrinolytic system due to its ability to serve as a receptor and activator of plasminogen on the cell surface of several cell-types such as leukocytes and neurons (By similarity). Stimulates immunoglobulin production (By similarity).

8. Phosphoenolpyruvate carboxykinase, cytosolic [GTP]
General function:
Energy production and conversion
Specific function:
Regulates cataplerosis and anaplerosis, the processes that control the levels of metabolic intermediates in the citric acid cycle. At low glucose levels, it catalyzes the cataplerotic conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle. At high glucose levels, it catalyzes the anaplerotic conversion of phosphoenolpyruvate to oxaloacetate.
