Host responses influence on the induction of lambda prophage
Inactivation of bacteriophage lambda CI repressor leads almost exclusively to lytic development. Prophage induction can be initiated either by DNA damage or by heat treatment of a temperature-sensitive repressor. These two treatments also cause a concurrent activation of either the host SOS or heat-shock stress responses respectively. We studied the effects of these two methods of induction on ...

Rapid confirmation of single copy lambda prophage integration by PCR by B. S. Powell, M. P. Rivas, D. L. Court, Y. Nakamura, C. L. Turnbough, Jr Nucleic Acids Research (1994), 22, 5765-5766. The publishers apologise for the incorporation of three errors, introduced during revisal of galley proofs for the above paper. The concentration of PCR primers used per reaction should read 500 nM each. Al...
متن کاملProphage induction of Escherichia coli (lambda) by N-nitrosamines.
Carcinogenic N-nitrosamines were tested for their ability to induce lambda in a lysogenic strain of Escherichia coli K-12 (58-161 F+ Dimethylnitrosamine, di-n-propylnitrosamine, methyl-n-propylnitrosamine, and N-nitrosopiperidine were shown to be inducers of prophage.
متن کاملEscherichia coli gal operon proteins made after prophage lambda induction.
Expression of the EScherichia coli gal operon under the control of the prophage lambda promoter pL leads to gross discoordinacy of gal expression. Expression of the most promoter-distal cistron galK is much greater than expression of the promoter-proximal cistron galE. We had previously shown that transcription of the gal operon is coordinate after prophage induction. A survey of protein synthe...
متن کاملChromosomal rearrangements in Escherichia coli strains carrying the cryptic lambda prophage.
T H E insertion of h into the chromosome of Escherichia coli K12 increases the distance between the loci gal and bio, bracketing the prophage. Thus the frequency of PI mediated joint transduction of gal and bio from a lysogenic donor is considerably lower than that from a non-lysogenic one (ROTHMAN 1965). Accordingly, the frequency of gal-bio cotransduction from a donor carrying a deletion in i...
