ICE family: SXT/R391
The SXT/R391 family was defined by Burrus et al (2006).They proposed that any ICE that encodes an integrase gene closely related to intSXT and that integrates into prfC be considered part of the SXT/R391 family of ICEs. In addition the tra genes, which encode the ICE conjugation apparatus, are also a defining feature of this family of ICEs. However, there are some exceptions for those that share a syntenic ‘core’ structure and features but have a different integrase
