Type II secretion system, protein N (IPR022792)

Short name: T2SS_protein-N

Overlapping homologous superfamilies


Family relationships



The secretion pathway (GSP) for the export of proteins (also called the type II pathway) [PMID: 8438237] requires a number of protein components. One of them is known as the 'N' protein and has been sequenced in a variety of bacteria such as Aeromonas hydrophila (gene exeN); Erwinia carotovora (gene outN); Klebsiella pneumoniae (gene pulN); or Vibrio cholerae (gene epsN). The size of the 'N' protein is around 250 amino acids. It apparently contains a single transmembrane domain located in the N-terminal section. The short N-terminal domain is predicted to be cytoplasmic and the large C-terminal domain periplasmic.
