Journal ArticleDOI
Prophage lambda at unusual chromosomal locations: I. Location of the secondary attachment sites and the properties of the lysogens
TL;DR: The integration, frequency of phage λ into a mutant host deleted for the normal prophage insertion site is reduced about 200-fold relative to integration into wild-type Escherichia coli.
Journal ArticleDOI
T4 endonuclease VII cleaves holliday structures
TL;DR: Observations account for the role of endonuclease VII in the DNA metabolism of phage T4, and provide the first example of an enzyme that acts specifically on branch points in duplex DNA.
Journal ArticleDOI
Overproduction of Escherichia coli integration host factor, a protein with nonidentical subunits.
TL;DR: Two strains are constructed in which the two subunits of IHF, encoded by the himA and hip genes of Escherichia coli, are expressed under the control of the lambda rho L promoter, resulting in milligram quantities of apparently homogeneous IHF.
Journal ArticleDOI
Site-specific Recombination in Phage Lambda
Robert A. Weisberg,Arthur Landy +1 more
TL;DR: A stable lysogen is formed when an infecting viral particle succeeds both in repressing lytic functions and in inserting its DNA in a quiescent form of the viral chromosome called prophage.
Journal ArticleDOI
Prophage lambda at unusual chromosomal locations. II. Mutations induced by bacteriophage lambda in Escherichia coli K12.
TL;DR: Most mutants of an Escherichia coli strain deleted for the primary λ attachment site was lysogenized with λ at secondary sites, and most mutants were pro, although certain other genes could be mutated at lower frequencies.
