Bacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects bacteria. It infects most strains of Escherichia coli and relies on these hosts to propagate. Bacteriophage T7 has …

Aug 20, 2019 · Using high-resolution cryo-electron microscopy and X-ray crystallography, here we describe various structures of the T7 bacteriophage portal and fiber-less tail complex, which …

Oct 29, 2024 · Explore the intricate structure, infection process, and replication of the T7 virus, highlighting its genetic regulation and biological significance. The T7 virus, a bacteriophage …

6 days ago · Studies on T7 phage show that within minutes of infection, host RNA polymerase is altered to favor viral transcription, accelerating replication. As replication progresses, structural …

T7 phage has drawn massive attention in precision medicine owing to its distinctive advantages, such as short replication cycle, ease in displaying peptides and proteins, high stability and …

Jan 1, 2016 · Initiation of DNA replication in phage T7 chromosome. The primary origin of phage T7 (position 14.75–15.0) contains two T7 RNA polymerase promoters, ϕ1.1A and ϕ1.1B, an …

Among these phage are the famous ‘T’ (for type) phage of E. coli B, which were assembled by Milislav Demerec with the help of Max Delbrück: phage T1 through T7. We present an …

Jan 15, 2020 · Bacteriophage T7 is an intracellular parasite that recognizes its host via its tail and tail fiber proteins, known as receptor-binding proteins (RBPs). The RBPs attach to specific...

Bacteriophage T7 is the simplest of the three systems with its replisome composed of a polymerase (gp5), helicase/primase (gp4) and ssDNA-binding protein (gp2.5) all encoded by …

Jan 10, 2013 · We used cryo–electron tomography to capture T7 virions at successive stages of infection of Escherichia coli minicells at ~4-nm resolution. The six phage tail fibers were folded …
