WebPOTRA (for polypeptide-transport-associated domain) is a novel domain identified in proteins of the ShlB, Toc75, D15 and FtsQ/DivIB families.In most cases, the POTRA domain is associated with a β-barrel outer membrane domain and its function has been experimentally related to polypeptide transport in Toc75 (Tic–Toc protein import system … Web1 dec. 1995 · Hemolysis by Serratia marcescens is caused by two proteins, ShlA and ShlB. ShlA is the hemolysin proper, and ShlB transports ShlA through the outer membrane, whereby ShlA is converted into a hemolysin. Superhemolytic ShlA derivatives that displayed 7- to 20-fold higher activities than wild-type ShlA were isolated. WebThe results demonstrate the orientation of large portions of ShlB in the outer membrane and suggest that ShLB may function as a specialized pore through which ShlA is secreted. The ShlB protein in the outer membrane of Serratia marcescens is the only protein known to be involved in secretion of the ShlA protein across the outer membrane.
