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

It consists of a pilin domain at the N-terminal, followed by a beta-repeat hinge-like domain and a C-terminal beta-sheet-rich domain, similar to H-type lectins [1,2]. This entry represents the ...	CofB is a minor pilin involved in type IV pili assembly. It consists of a pilin domain at the N-terminal, followed by a beta-repeat hinge-like domain and a C-terminal beta-sheet-rich domain, similar to H-type lectins [1,2]. This entry represents the C-terminal domain which is required for CofB to initiate pilus assembly [1,2].	Domain
