Phage lambda repressors

Gronenbom, B. (1976) Overproduction of the phage lambda repressor under control of the lac promoter of Escherichia coh Mol. Gen. Genet 148,243—250. 

Figure 28-11 Genetic and physical map of the X phage genome. After Szybalski. See Honigman et al.255 for a more detailed diagram of the immunity region. The gene for the lambda repressor is labeled C[.

Figure 8.1 A region of DNA in the related bacteriophages lambda, 434, and P22 that controls the switch for synthesis of new phage particles. Two structural genes are involved in this switch one coding for a repressor protein and one coding for the Cro protein. Between these genes there is an operator region (OR) that contains three protein binding sites—ORl, OR2, and OR3.
