Protein Domain : IPR000983

Type:  Family Name:  Bacterial general secretion pathway protein G-type pilin
Description:  The general (type II) secretion pathway (GSP) within Gram-negative bacteria is a signal sequence-dependent process responsible for protein export [, , ]. The process has two stages, exoproteins are first translocated across the inner membrane by the general signal-dependent export pathway (GEP), and then across the outer membrane by a species-specific accessory mechanism. Several proteins are involved in the GSP, one of these is termed general secretion pathway protein G (GSPG). This protein shares several sequence similarities with bacterial fimbrial protein, or pilin, the major structural protein of pili [, ]. Pili are polar flexible filamentous adhesions ~2500 nm in length, and diameter ~5.4 nm. Fimbrial and GSPG proteins share the following characteristics; a methylated, hydrophobic N-terminal residue; a hydrophobic leader peptide of 5-10 residues, terminating with glycine; glutamate as the fifth residue of the mature sequence; and a highly hydrophobic N terminus.
