Function | Component of the conjugative T4SS trb/tra required for the transfer of plasmid F among E. coli cells, from donor cells to recipients. The TrbI could be involved in pilus expression, although mutations in trbI do not block pilus production. |
Miscellaneus | Insertions in trbI permit normal levels of plasmid transfer but reduce the efficiency of RNA and DNA phage infection. Interestingly, expression of TrbI in excess has a similar effect, and some trbI::kan mutants express extremely long pili, suggesting that the kinetics of pilus extension and retraction could be altered in these strains.
