Multiphosphoryl transfer protein

Gene

Organism
Escherichia coli O157:H7
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-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
Contains 1 HPr domain.PROSITE-ProRule annotation
Contains 1 PTS EIIA type-2 domain.PROSITE-ProRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
