Catalytic domain of plasmid pAD1 relaxase TraX defines a group of relaxases related to restriction endonucleases

31 Jul 2013

Abstract excerpt

Plasmid pAD1 is a 60-kb conjugative element commonly found in clinical isolates of Enterococcus faecalis. The relaxase TraX and the primary origin of transfer oriT2 are located close to each other and have been shown to be essential for conjugation. The oriT2 site contains a large inverted repeat (where the nic site is located) adjacent to a series of short direct repeats. TraX does not show any of the typical...
