T7-like viruses
Did you know?
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 a lytic life cycle, meaning that it destroys the cell it infects. It also possesses several properties that make it an ideal phage for … See more In a 1945 study by Demerec and Fano, T7 was used to describe one of the seven phage types (T1 to T7) that grow lytically on Escherichia coli; although all seven phages were numbered arbitrarily, phages with odd numbers, … See more The virus has complex structural symmetry, with a capsid of the phage that is icosahedral (twenty faces) with an inner diameter of 55 nm and a tail 19 nm in diameter and 28.5 … See more T7 has a life cycle of 17 min at 37˚C, i.e. the time from infection to the lysis of the host cell when new phage are released. Due to the short latent period, most physiological … See more The T7 promoter sequence is used extensively in molecular biology due to its extremely high affinity for T7 RNA polymerase and thus high level of expression. T7 has been used as a model in synthetic biology. … See more T7 grows on rough strains of Escherichia coli (i.e. those without full-length O-antigen polysaccharide on their surface) and some other enteric bacteria, but close relatives also infect smooth and even capsulated strains. E. coli is more resistant to T7 than to some other … See more The genome of phage T7 was among the first completely sequenced genomes and was published in 1983. The head of the phage particle contains the roughly 40 kbp dsDNA genome … See more Phage T7 has the simplest known DNA replisome, consisting of a helicase and primase that reside in a single polypeptide chain that forms a hexamer in the presence of DNA and ATP or dTTP. T7 DNA polymerase, assisted by E. coli thioredoxin, performs both See more WebT7likevirus (synonyms T7 phage group, T7-like phages, and T7-like viruses) is a genus of viruses in the order Caudovirales, in the family Podoviridae, in the subfamily …
