>TIGR02738 TrbB type-F conjugative transfer system pilin assembly thiol-disulfide isomerase TrbB; InterPro: IPR014109 This entry includes thiol-disulphide isomerase (TrbB), a protein that is involved in conjugative transfer of plasmid DNA, specifically in the F-type system. TrbB has been predicted to contain a thioredoxin fold, it also contains a conserved pair of cysteines and has been shown to function as a thiol disulphide isomerase by complementation of Escherichia coli DsbA mutants . TtbB is believed to be involved in pilin assembly . TrbB is closely related to TraF (IPR014110 from INTERPRO) though somewhat longer lacking the cysteine motif and is apparently not functional as a disulphide bond isomerase..
