Protein attributes

Sequence length	161 AA.
Sequence status	Complete.
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 By similarity.
Catalytic activity	Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine.
Subcellular location	Cytoplasm By similarity.
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.
