Conjugative transfer of Tn916 in Enterococcus faecalis: trans activation of homologous transposons.


Tn916 [carries tet(M)] is a 16.4-kb conjugative transposon that can establish itself in multiple copies in Enterococcus faecalis. To study the interaction of coresident homologous transposons during conjugation, an E. faecalis mutant defective in homologous recombination was utilized for construction of strains harboring Tn916 delta E (a derivative in which… (More)
