The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

Enzyme Commission Primary Name: phosphoenolpyruvate—protein phosphotransferase

Enzyme Commission Synonyms: phosphoenolpyruvate sugar phosphotransferase enzyme I, phosphopyruvate-protein factor phosphotransferase, phosphopyruvate-protein phosphotransferase, sugar-PEP phosphotransferase enzyme I, phosphoenolpyruvate:protein-L-histidine N-pros-phosphotransferase

Enzyme Commission Summary:
Enzyme I of the phosphotransferase system (cf. EC 2.7.1.69, protein-Nπ-phosphohistidine—sugar phosphotransferase). Acts only on histidine residues in specific phosphocarrier proteins of low molecular mass (9.5 kDa) involved in bacterial sugar transport. A similar reaction, where the protein is the enzyme EC 2.7.9.2, pyruvate, water dikinase, is part of the mechanism of that enzyme.
