A novel antivirulence element in the temperate bacteriophage HK022.

Journal of bacteriology - 1 Dec 1993

Carlson N G, Little J W

Abstract excerpt

Lysogens of the temperate lambdoid phage HK022 are immune to superinfection by HK022. Superinfection immunity is conferred in part by the action of the HK022 CI repressor at the O.R operators. In this work, we have identified an additional regulatory element involved in immunity. This site, termed OFR (operator far right), is located just downstream of the cro gene, more than 250 nucleotides distant from OR. The...
