General annotation (Comments)
| Function | Multifunctional protein that includes general (non sugar-specific) and sugar-specific components 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. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr). HPr transfers the phosphoryl group to the phosphoryl carrier EIIA, which then transfers it to EIIB By similarity. |
| Catalytic activity | Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine. Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine. |
| Cofactor | Magnesium By similarity. |
| Subcellular location | Cytoplasm Probable. |
| Domain | The EIIA domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the EIIB domain. The Enzyme I (EI) N-terminal domain contains the HPr binding site, the central domain the pyrophosphate/phosphate carrier histidine, and the C-terminal domain the pyruvate binding site By similarity. |
| Miscellaneous | The Enzyme I (EI) reaction takes place in three steps, mediated by a phosphocarrier histidine residue located on the surface of the central domain. The two first partial reactions are catalyzed at an active site located on the N-terminal domain, and the third partial reaction is catalyzed at an active site located on the C-terminal domain. For catalytic turnover, the central domain swivels from the concave surface of the N-terminal domain to that of the C-terminal domain By similarity. |
| Sequence similarities | Belongs to the PEP-utilizing enzyme family. Contains 1 HPr domain. Contains 1 PTS EIIA type-2 domain. |
