InterPro entry IPR008731
This sequence identifies proteins which are a component of the phosphoenolpyruvate:sugar phosphotransferase system (PTS), a major carbohydrate active transport system. 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 [PUBMED:8246840]. This entry represents the N-terminal domain of enzyme I (EIN) which 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. The N-terminal domain of EI (EIN) extends from residues 1 to 259 and can be phosphorylated in a fully reversible manner by phosphorylated HPr. EIN, however, cannot be autophosphorylated by PEP [PUBMED:1655788, PUBMED:8031118].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the PEP-utilisers_N domain has been found. There are 22 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
