Protein
Multiphosphoryl transfer protein
Gene
fruB, HI_0448
Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.

Catalytic activityi

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

Domaini

In contrast to classical PTS systems, the fructose PTS has no requirement for HPr; FPr combines a IIA domain with two HPr domains.1 Publication
The EIIA domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the EIIB domain.1 Publication

Sequence similaritiesi

Contains 2 HPr domains.
