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 By similarity.

Catalytic activity

Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine.

Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.

Subcellular location

Cell 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.

The EIIA domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the EIIB domain.

Sequence similarities

Contains 1 PTS EIIA type-1 domain.

Contains 1 PTS EIIB type-1 domain.

Contains 1 PTS EIIC type-1 domain.
