TLDR
Two types of spontaneous and NTG-induced mutants of Escherichia coli 594 insensitive to the lethal action of λ P gene were isolated and called rpl, showing different phenotypes.About:

Phage Lambda P Protein: Trans-Activation, Inhibition Phenotypes and their Suppression
TL;DR: It is observed that ColE1 replication and plasmid establishment upon transformation is extremely sensitive to P, and this effect is distinguished from P-lethality directed to cells, and it is shown that alleles of dnaB protect the variant cells from P expression.
Journal ArticleDOI
Acquired mutations in phage λ genes O or P that enable constitutive expression of a cryptic λN+cI[Ts]cro- prophage in E. coli cells shifted from 30°C to 42°C, accompanied by loss of immλ and Rex+ phenotypes and emergence of a non-immune exclusion-state
TL;DR: In this article, the authors examined the scope of the Nie exclusion-state toward λ mutants blocked for lysogeny, and λ hybrids substituted for immunity or replication genes.
Journal ArticleDOI
3-Phenyllactic acid production by Lactobacillus crustorum strains isolated from naturally fermented vegetables
TL;DR: In this paper, the 3-Phenyllactic acid (3-PLA) is a bioactive compound with broad spectrum antibacterial and antifungal activity and several desirable pharmacological properties.

Termination Factor for RNA Synthesis
TL;DR: A new protein has been isolated from E. coli which causes specific termination and release of RNA during synthesis in vitro and has been given the name ρ-factor.
Journal ArticleDOI
A new bacterial gene (groPC) which affects lambda DNA replication.
TL;DR: A bacterial mutation affecting λ DNA replication, called groPC756, has been mapped between the thr and leu bacterial loci as mentioned in this paper, and it is shown that the mutation at the groPC locus also interferes with bacterial growth at 42°C.
Journal ArticleDOI
Specialized nucleoprotein structures at the origin of replication of bacteriophage lambda. Protein association and disassociation reactions responsible for localized initiation of replication.
TL;DR: The initiation of lambda DNA replication requires ordered assembly and partial disassembly of specialized nucleoprotein structures, and the disassembly activity of DnaK and DnaJ may be their general role in the heat shock response.
Journal ArticleDOI
A new host gene (groPC) necessary for lambda DNA replication.
TL;DR: The isolation of a bacterial mutation in a gene, designated groPC, which affects the growth of phages lambda and P2, is described and the possibility that the groPC gene is concerned with host DNA replication is discussed.

Constitutive λ DNA replication by λc17, a regulatory mutant related to virulence
S. Packman,William S. Sly +1 more
TL;DR: A model is presented that proposes that those λc17 genes which are subject to cI repression in the immune host can be derepressed if phage replication produces too many phage chromosomes for the cI repressor to control.
