Multiphosphoryl transfer protein

Gene

fryA

Organism
Escherichia coli O157:H7
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Multifunctional protein that includes general (non sugar-specific) and sugar-specific components of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FryABC PTS system is involved in fructose transport.By similarity

Catalytic activityi

Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine.By similarity
[Protein]-N(pi)-phospho-L-histidine + D-fructose(Side 1) = [protein]-L-histidine + D-fructose 1-phosphate(Side 2).By similarity

Domaini

The PTS EIIA type-2 domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the PTS EIIB type-2 domain.PROSITE-ProRule annotation
In contrast to classical PTS systems, the fructose-like PTS has no requirement for HPr and Enzyme I; FryA combines a IIA domain with an Enzyme I and a HPr domains.Curated

Sequence similaritiesi

Belongs to the PEP-utilizing enzyme family.Curated
