Fy. An et Db. Clewell, THE ORIGIN OF TRANSFER (ORIT) OF THE ENTEROCOCCAL, PHEROMONE RESPONDING, CYTOLYSIN PLASMID PAD1 IS LOCATED WITHIN THE REPA DETERMINANT, Plasmid, 37(1), 1997, pp. 87-94
The highly conjugative pAD1 plasmid encodes a mating response to the p
eptide sex pheromone cAD1 secreted by recipient strains of Enterococcu
s faecalis. The location of the origin of transfer (oriT) was determin
ed through the ability to mobilize the Escherichia coli-E. faecalis sh
uttle plasmid pAM401 carrying specific segments of pAD1. The oriT sequ
ence was found to be completely within the repA determinant known to b
e required for plasmid maintenance. (C) 1997 Academic Press.
