FIGURE 2

Phylogenetic analysis of ICEs and dICE belonging to the ConjTn916 superfamily. (A) Relaxases; (B) coupling proteins; (C) VirB4 proteins. Bootstrap supports are given as followed: ML/BioNJ. X marks the nodes that are not validated with BioNJ. ICE names are colored according to the family of conjugation module they encode: orange = ConjTn916, green = ConjICESt3 (including elements encoding relaxases related to the one of ICE_SmuA159_tRNAleu in bold dark green). Because of their very close phylogenetic relationships, relaxases (A), CP (B), and VirB4 (C) of only three ICEs representative of the ConjTn916 family are shown. Refer to Supplementary Table S1 for ICE/dICE and strain details.
