Conserved Site

Type II secretion system GspD, conserved site (IPR004845)

Short name: T2SS_GspD_CS


A number of proteins are involved in the general secretion pathway (GSP); one of these is known as protein D (GSPD protein). Protein D is involved in the type II general secretion pathway within Gram-negative bacteria, a signal sequence-dependent process responsible for protein export [PMID: 8438237, PMID: 1365398, PMID: 1592799,PMID: 8326859, PMID: 7901733, PMID: 7934814, PMID: 8190064]. The most probable location of protein D is the outer membrane [PMID: 2677007]. This suggests that protein D constitutes the apparatus of the accessory mechanism, and is thus involved in transporting exoproteins from the periplasm, across the outer membrane, to the extracellular environment.
