Domain

Polypeptide-transport-associated, ShlB-type (IPR013686)

Short name: Polypept-transport_assoc_ShlB

Domain relationships

None.

Description

The POTRA domain (for polypeptide-transport-associated domain) is found towards the N terminus of ShlB family proteins (IPR005565). ShlB is important in the secretion and activation of the haemolysin ShlA. It has been postulated that the POTRA domain has a chaperone-like function over ShlA; it may fold back into the C-terminal beta-barrel channel [PMID: 14559180].
