Organism

Escherichia coli (strain K12) [Reference proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia › Escherichia coli

Protein attributes

Sequence length	133 AA.
Sequence status	Complete.
Protein existence	Uncertain

General annotation (Comments)

Function	The phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane. This system is involved in N-acetylgalactosamine transport.
Subcellular location	Cell inner membrane; Multi-pass membrane protein. Note: When overexpressed.
Domain	The EIIC domain forms the PTS system translocation channel and contains the specific substrate-binding site.
Sequence similarities	Contains 1 PTS EIIC type-4 domain.
Caution	Could be the product of a pseudogene.
