Homologous Superfamily

PtsI, HPr-binding domain superfamily (IPR036618)

Short name: PtsI_HPr-bd_sf

Overlapping entries


This superfamily describes a domain that can be found in the N terminus of PtsI, a component of the phosphoenolpyruvate:sugar phosphotransferase system (PTS). The PTS system is found throughout the bacterial kingdom, and is responsible for the coupled phosphorylation and translocation of numerous sugars across the cytoplasmic membrane [PMID: 8246840]. PtsI transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr) which in turn phosphorylates a group of membrane-associated proteins, known as enzyme II [PMID: 1655788, PMID: 8031118].

This region contains a SAM domain-like fold.
