T4 is a sort of bacteriophage that infects of E. coli.
The bacteriophage T4 capsid is a prolonged icosahedron, 120 nm long and 86 nm wide, and is worked with three essential proteins such as gp23*, which shapes the hexagonal capsid cross section, gp24*, which structures pentamers at eleven of the twelve vertices.
gp20, which frames the extraordinary dodecameric entry vertex through which DNA.
T4 DNA Ligase is ligation catalyst which utilized the parts of DNA by the catalyzing between compared 5'phosphate and 3' hydroxyl ends and phosphodiester bonds in the double stranded DNA utilizing ATP as a coenzyme.
