Protein

Fructose-like PTS system EIIBC component

Gene

frvB

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -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. The enzyme II FrvAB PTS system is involved in fructose transport.1 Publication

Catalytic activityi

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

Domaini

The PTS EIIB type-2 domain is phosphorylated by phospho-EIIA on a cysteinyl residue. Then, it transfers the phosphoryl group to the sugar substrate concomitantly with the sugar uptake processed by the PTS EIIC type-2 domain.PROSITE-ProRule annotation
The EIIC type-2 domain forms the PTS system translocation channel and contains the specific substrate-binding site.PROSITE-ProRule annotation
