Sequence Analysis of a Hybrid HK022/λ Bacteriophage and the Precise Identification of the λb515 and λb519 Deletion Endpoints

摘要

Bacteriophage O276 is a laboratory-generated hybrid that carries the immunity region of bacteriophage HK022 and all remaining genes from phage λ. Its construction was instrumental in the discovery of RNA-mediated antitermination, an intriguing alternative to the protein-mediated mechanism of transcription antitermination found in most lambdoid phages.
