Abstract excerpt
Pheromone-induced conjugal transfer of the hemolysin-bacteriocin plasmid pAD1 of Enterococcus faecalis is regulated by a cluster of determinants designated traA, traB, and regions C and E. The E region is believed to include a positive regulator that controls many structural genes related to conjugation. The pheromone-inducible Tn917-lac fusion NR5, located in the E region, is regulated by the products of traA,...
