Identification
Name:Phosphoenolpyruvic acid
DescriptionPhosphoenolpyruvate (PEP) plays a key role in many metabolic reactions. It has a high energy phosphate bond, and is involved in glycolysis and gluconeogenesis. In glycolysis, PEP is formed by the action of the enzyme enolase on 2-phosphoglycerate. Metabolism of PEP to pyruvate by pyruvate kinase (PK) generates 1 molecule of adenosine triphosphate (ATP) via substrate-level phosphorylation. ATP is one of the major currencies of chemical energy within cells. In gluconeogenesis, PEP is formed from the decarboxylation of oxaloacetate and hydrolysis of 1 guanosine triphosphate molecule. This reaction is catalyzed by the enzyme phosphoenolpyruvate carboxykinase (PEPCK). This reaction is a rate-limiting step in gluconeogenesis. (wikipedia)

Specific function:
Catalyzes the reversible conversion of 2- phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis.

Reactions
Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine.
Protein HPr N(pi)-phospho-L-histidine + protein EIIA = protein HPr + protein EIIA N(tau)-phospho-L-histidine.
Protein EIIA N(pi)-phospho-L-histidine + dhaL-ADP = protein EIIA + dhaL-ATP.
General function:
Involved in sugar:hydrogen symporter activity
Specific function:
General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the permease (enzymes II/III)
