| Protein existence | Inferred from homology. |
General annotation (Comments)
| Function | The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in glucose transport. This enzyme is also a chemoreceptor monitoring the environment for changes in sugar concentration By similarity. |
| Catalytic activity | Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate. |
| Subcellular location | Cell inner membrane; Multi-pass membrane protein By similarity. |
| Domain | The EIIC domain forms the PTS system translocation channel and contains the specific substrate-binding site. The EIIB domain is phosphorylated by phospho-EIIA on a cysteinyl or histidyl residue, depending on the transported sugar. Then, it transfers the phosphoryl group to the sugar substrate concomitantly with the sugar uptake processed by the EIIC domain. |
| Sequence similarities | Contains 1 PTS EIIB type-1 domain. Contains 1 PTS EIIC type-1 domain. |
