		| 1stcategory | 		P-T4SS | 
			2ndcategory | 		TraB Family | 
		| 3rdcategory | 		Conjugation | 
		| Function | 					Functions as a Dtr protein required for the conjugal transfer of the plasmid pTiC58. | 
		| Miscellaneus | 				It was proposed that an ancestor of the pTiC58 plasmid may have arisen by the fusion of two conjugal plasmids and that one (IncP-type) tra system in this fusion retained the original function while the other (IncN-type) could have evolved to transfer DNA to plant nuclei.
TraB is member of the TraR regulon and is transcribed as traAFBH operon that is repressed by formation of a putative relaxosome at oriT consisting the TraA, TraC and TraD.
