{PDOC00879} {PS01142; T2SP_N} {BEGIN} ********************************************************** * Bacterial type II secretion system protein N signature * ********************************************************** 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. -Consensus pattern: G-T-L-W-x-G-x(11)-L-x(4)-W -Sequences known to belong to this class detected by the pattern: ALL. -Other sequence(s) detected in Swiss-Prot: NONE. -Last update: November 1995 / First entry.
