Overlapping homologous superfamilies


Family relationships


This entry represents the bacterial F pilus assembly protein TraL [PMID: 6120442, PMID: 12003924]. The F-pilus appears to be involved in recipient cell recognition during the establishment of a stable mating pair before conjugation, as well as forming part of the conjugative pore for DNA transfer [PMID: 11849547]. The F-pilus is the site of attachment of the filamentous phages (M13, f1 and fd), which attach to the F-pilus tip, and the RNA phages, R17 and Qbeta, which attach to different sites exposed on the sides of the pilus.
