Protein attributes

Sequence length106 AA.
Sequence statusComplete.
Protein existenceInferred 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 By similarity.

Catalytic activity

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

Subcellular location

Cytoplasm Potential.

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.

Sequence similarities

Contains 1 PTS EIIB type-2 domain.
