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 fructose transport.

Catalytic activity

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

Subcellular location

Cell inner membrane; Multi-pass membrane protein Ref.7.

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.

The EIIC domain forms the PTS system translocation channel and contains the specific substrate-binding site.

Sequence similarities

Contains 1 PTS EIIB type-2 domain.

Contains 1 PTS EIIC type-2 domain.
