This domain is found in CofB from Escherichia coli and in similar proteins predominantly from proteobacteria. CofB is a minor pilin, required for assembly of Type IV pili. This entry represents the pilin domain, which is located in the N-terminal region of the protein. It shows a canonical T4b pilin fold seen in the major pilins, with an alpha-helical backbone and a five-stranded anti- parallel beta-sheet [1,2].	Domain
