The antigenic structure of lambda bacteriophage
Virology, 1965Abstract Multiple antigenic components on the surface of lambda bacteriophage have been demonstrated by means of rabbit antiserum prepared against pyrophosphate ruptured lambda c. Three antigens can be detected by their C′ fixing activity (main and secondary components), and another, distinct from the main component, by its ability to react with ...

Regulatory Circuits of Bacteriophage Lambda
1981Publisher Summary This chapter summarizes the regulatory systems of λ to point out that both of its developmental pathways follow finely tuned temporal control mechanisms far more sophisticated than those conceived in the past decades. The chapter also emphasizes the salient features of the complex processes, such as: how a multivalent operator makes

Two repressors in bacteriophage lambda
Molecular and General Genetics MGG, 1973The functions of anti-immunity and immunity are very similar: both repress the early functions acting on the same two operators, oL and oR. They differ only in their effect on the expression of the cI gene.

On inactivation of bacteriophage lambda by hydroxylamine
Mutation Research, 1980Hydroxylamine is a mutagen which is much more active on single-stranded DNA than on double-stranded DNA. It is shown here that the cohesive ends of lambda DNA, with 10 cytidine residues, constitute a hydroxylamine target roughly equal in magnitude to the entire duplex part of the molecule, which contains ca. 25 000 cytidine residues.

Structure and Assembly of Bacteriophage Lambda
1977Bacteriophage λ has an icosahedral head with a radius of 30 nm and a flexible tail 150 nm long (Fig. lb; Kellenberger, 1961; Eiserling and Boy de la Tour, 1965; Kemp et al., 1968; Eiserling as quoted in Kellenberger and Edgar, 1971; Bayer and Bocharov, 1973; Mazza and Felluga, 1973; Harrison et al., 1973).

Switches in Bacteriophage Lambda Development
Annual Review of Genetics, 2005The lysis-lysogeny decision of bacteriophage lambda (λ) is a paradigm for developmental genetic networks. There are three key features, which characterize the network. First, after infection of the host bacterium, a decision between lytic or lysogenic development is made that is dependent upon environmental signals and the number of infecting phages ...

Modifying Bacteriophage $\lambda$ with Recombineering
2009Recombineering is a recently developed method of in vivo genetic engineering used in Escherichia coli and other Gram-negative bacteria. Recombineering can be used to create single-base changes, small and large deletions, and small insertions in phage lambda as well as in bacterial chromosomes, plasmids, and bacterial artificial chromosomes (BACS). This

Densities of transducing lambda bacteriophages
Journal of Molecular Biology, 1961Phages of a lysate of an induced culture of bacteria lysogenic for λ when centrifuged in a CsCl density gradient form a narrow band having a maximum at a definite density. The rare galactose-transducing phages contained in such a lysate are shown here to form a much wider band (especially towards the lower densities) having no definite maximum.

The kil gene of bacteriophage lambda
Virology, 1975A new phage λ gene, called kil, has been identified. It is required for killing its host under certain conditions. Kil expression is dependent upon the positive regulator gene N and can be observed in an induced defective lysogen which is deficient in DNA replication.
