Influence of the Escherichia coli oxyR gene function on lambda prophage maintenance [PDF]

, 2010
In Escherichia coli hosts, hydrogen peroxide is one of the factors that may cause induction of lambda prophage. Here, we demonstrate that H2O2-mediated lambda prophage induction is signiWcantly enhanced in the oxyR mutant host. The mRNA levels for cI

The NMR structure of the Orf63 lytic developmental protein from lambda bacteriophage

Scientific Reports
The orf63 gene resides in a region of the lambda bacteriophage genome between the exo and xis genes and is among the earliest genes transcribed during infection.

Bacterial Virus Lambda Gpd-Fusions to Cathelicidins, α- and β-Defensins, and Disease-Specific Epitopes Evaluated for Antimicrobial Toxicity and Ability to Support Phage Display

Viruses, 2019
We showed that antimicrobial polypeptides, when translated as gene fusions to the bacteriophage lambda capsid decoration protein gpD, formed highly toxic molecules within E.

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

Molecular Microbiology, Volume 126, Issue 5, Page 503-518, November 2026.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Identification of a panel of tumor-associated antigens from breast carcinoma cell lines, solid tumors and testis cDNA libraries displayed on lambda phage

BMC Cancer, 2004
Background Tumor-associated antigens recognized by humoral effectors of the immune system are a very attractive target for human cancer diagnostics and therapy. Recent advances in molecular techniques have led to molecular definition of immunogenic tumor

A Lambda Red Recombinase‐Assisted CRISPR/Cas9 System for Efficient and Precise Genome Editing in Agrobacterium tumefaciens

Plant Biotechnology Journal, Volume 24, Issue 11, Page 6010-6027, November 2026.
ABSTRACT Agrobacterium tumefaciens is a powerful delivery tool for plant genetic transformation and a pivotal platform for agricultural biotechnology. However, laboratory strains of Agrobacterium have remained genetically unoptimized for decades, with genome engineering hindered by inefficient, endogenous homologous recombination systems.

The Escherichia coli heat shock response and bacteriophage lambda development

, 1995
The Escherichia coli/bacteriophage lambda genetic interaction system has been used to uncover the existence of various biological machines. The starting point of all these studies was the isolation and characterization of E.

Construction from Mu d1 (lac Apr) lysogens of lambda bacteriophage bearing promoter-lac fusions: isolation of lambda ppheA-lac

, 1982
Bacteriophage Mu d1 (lac Aprr) was used to obtain strains of Escherichia coli K-12 in which the lac genes are expressed from the promoter of pheA, the structural gene for the enzyme chorismate mutase P-prephenate-dehydratase.

ICP0 antagonizes ICP4-dependent silencing of the herpes simplex virus ICP0 gene.

PLoS ONE, 2010
ICP0 is a regulatory protein that plays a critical role in the replication-latency balance of herpes simplex virus (HSV). Absence of ICP0 renders HSV prone to establish quiescent infections, and thus cellular repressor(s) are believed to silence HSV mRNA
