The Big Picture Book of Viruses: Myoviridae



Taxonomy: Taxonomic structure of the family. Genus "T4-like phages", Genus "P1-like phages", Genus "P2-like phages", Genus "Mu-like phages", Genus "SP01-like Phages" and Genus "PhiH-like viruses".

Host: Virus infects bacteria.

Genome: Virions contain 48 % nucleic acid. Virions contain one molecule of linear double stranded DNA. Total genome length is 336000 nt. Double stranded DNA circularly permuted. Genome sequence has terminal repeated sequences. Guanine + cytosine ratio 35 %. Special nucleotides found in genome, are 5-hydroxy-methyl cytosine (instead of thymidine).

Morphology: Virions not enveloped; tailed; head. Head separated from tail by a neck, tail complex, consisting of a central tube and a contractile sheath, provided with a collar, base plate, 6 short spikes and 6 long fibers. Contraction seems to require ATP. Nucleocapsids isometric to quasi-isometric elongated; 95-111 nm long; 65-80 nm in diameter. Symmetry icosahedral. Nucleocapsids appear to be angular. 152 capsomers per nucleocapsid. Tail contractile; 80-455 nm long; 16 nm wide.
