Brief Introduction
FlhB is a membrane protein that is part of the flagellum-specific secretion apparatus. It is required for secretion of flagellar proteins, and for bacterial motility. FlhB is paralogous to a protein in the virulence type III secretion system. FlhB has a hydrophobic integral membrane domain, predicted to have four transmembrane helices, a flexible linker that is highly conserved and essential for function, and a cytoplasmic domain. The present study reports the structures of the cytoplasmic domains of two bacterial taxa. (Please see the publication for a more detailed introduction.)
