ORF information
ORF ID TF00780 (frame 1) Gene ID BAA97948
Position and sequences 1...475(475 aa) Gene Name/synonym trbI -
Organism Plasmid F Cluster 22 genes
Product F-type conjugal transfer protein TraB
1stcategory F-T4SS 2ndcategory TrbI-like-F Protein 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 TraB is required for piliation and transfer of DNA.
Miscellaneus TraB is predicted to be a hydrophilic protein that extends into the periplasmic space and is anchored in the inner membrane via a single transmembrane segment near the N terminus. The high concentrations of glycine and proline in TraB are characteristic of proteins with an extended conformation, such as VirB10 and TonB.
