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 mannitol transport (By similarity).
  • CATALYTIC ACTIVITY: Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine.
  • CATALYTIC ACTIVITY: Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.
  • SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein (Potential).
  • DOMAIN: The EIIC domain forms the PTS system translocation channel and contains the specific substrate-binding site.
  • DOMAIN: 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.
  • DOMAIN: The EIIA domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the EIIB domain.
  • PTM: An intramolecular phosphotransfer takes places between His-563 and Cys-386 (By similarity).
  • SIMILARITY: Contains 1 PTS EIIA type-2 domain.
  • SIMILARITY: Contains 1 PTS EIIB type-2 domain.
  • SIMILARITY: Contains 1 PTS EIIC type-2 domain.
