Protein

PTS system fructose-specific EIIABC component

Gene

fruA

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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]-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
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
