Genes for the establishment and maintenance of lysogeny by the temperate coliphage 186.

Department of Biochemistry, University of Adelaide, Australia.

ABSTRACT

To identify the genes in coliphage 186 that are required for lysogeny, we isolated clear-plaque mutants. Complementation studies and DNA sequencing identified two genes, the cI gene for the immunity maintenance repressor and the cII gene, which is required only for the establishment of lysogeny. One mutant carried a change in the LexA-binding site controlling expression of the antirepression protein Tum.
