GspD is a type II general secretion pathway protein involved in protein export. This is the N0 domain found at the N-terminal of GspD type II secretins and its close homologues [1-5]. These proteins form a dodecameric ring, in which the N0 domain mediate extensive contacts suggesting that dodecameric N0 ring is an important feature of T2SS secretins [4]. This domain is also found in virion export proteins, proteins thought to form a channel across the host outer membrane for the purposes of extruding the bacteriophage.	Domain
