The secretion pathway (GSP) for the export of proteins (also called the type II pathway) [1] 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 (gene exeN); Erwinia (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. As a signature pattern, we selected a conserved region in the N-terminal part of these proteins.
