Interaction between the sbcC gene of Escherichia coli and the gam gene of phage lambda.
gam mutants of phage lambda carrying long palindromes fail to form plaques on wild-type Escherichia coli but do grow on strains that are mutant in the sbcC gene. gam + lambda carrying the same palindrome grow on both hosts and on a host deleted for the recB, C and D genes. These results suggest that the Gam protein of lambda, known to interact also with E. coli's recBCD protein, can interact wi...
متن کاملMapping of integration and excision crossovers in superinfection double lysogens for phage lambda in Escherichia coli.
I N a previous paper it was shown that one prophage apparently acts as a homology region for a superinfecting phage of the same kind (CALEF, MARCHELLI, GUERRINI 1965). A more rigorous test for the same possibility can be obtained by correlating the frequency of integration of superinfecting phage at any given region with the map length of that region. The work presented here consists primarily ...
متن کاملCell growth and lambda phage development controlled by the same essential Escherichia coli gene, ftsH/hflB.
The lambda phage choice between lysis and lysogeny is influenced by certain host functions in Escherichia coli. We found that the frequency of lambda lysogenization is markedly increased in the ftsH1 temperature-sensitive mutant. The ftsH gene, previously shown to code for an essential inner membrane protein with putative ATPase activity, is identical to hflB, a gene involved in the stability o...
متن کاملInteractions between phage-shock proteins in Escherichia coli.
Expression of the pspABCDE operon of Escherichia coli is induced upon infection by filamentous phage and by many other stress conditions, including defects in protein export. Expression of the operon requires the alternative sigma factor sigma54 and the transcriptional activator PspF. In addition, PspA plays a negative regulatory role, and the integral-membrane proteins PspB and PspC play a pos...
متن کاملInducibility of lambda phage development in Escherichia coli mutants thermosensitive for DNA replication.
In a thermosensitive dnaZ mutant lysogenic for lambda, induction of the prophage development was provoked at the restrictive temperature. In dnaD strain, spontaneous release of lambda proceeded even at 43 degrees C, but distinct induction of the prophage development was not caused by a heat treatment. Similarly, shift up of growth temperature did not lead to induction of lambda in lysogens carr...
