ORF ID TF01768 (frame 1) Gene ID BAA97955
Position and sequences 1...128(128 aa) Gene Name/synonym trbI -
Organism Plasmid F Cluster 2 genes
Product F-type conjugal transfer protein TrbI
1stcategory F-T4SS 2ndcategory TrbI-F Family
3rdcategory Conjugation
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.
