The total sequence length ranges from 7,826 (in phage pMC8) to 509,170 bp (in phage pHS181) with the GC content of these phage being an average of 38.25%. [6] Within Bacillus phage there are 12 clusters (A-L), 28 subclusters, and 14 singletons. Clusters are groups of related genomes with the 12 clusters showing at least 50% homology between ...

Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.
Schematic drawing of a Φ29 phage virion (cross section and side view). The structure of Φ29 is composed of seven main proteins: the terminal protein (p3), the head or capsid protein (p8), the head or capsid fiber protein (p8.5), the distal tail knob (p9), the portal or connector protein (p10), the tail tube or lower collar proteins (p11), and the tail fibers or appendage proteins (p12*).
Bacillus virus G is a bacteriophage (phage) that infects Bacillus bacteria. The phage has been reported to have the largest genome of all discovered Myoviridae with nearly 700 protein-coding genes. [ 1 ]
The polymerase is a monomeric protein with two distinct functional domains. Site-directed mutagenesis experiments support the proposition that this protein displays a structural and functional similarity to the Klenow fragment of the Escherichia coli Polymerase I enzyme; [3] it comprises a C-terminal polymerase domain and a spatially separated N-terminal domain with a 3'-5' exonuclease activity.
Structure of phage ΦX174 capsid Schematic drawing of a Sinsheimervirus (aka Phix174microvirus) virion. The phi X 174 (or ΦX174) bacteriophage is a single-stranded DNA virus that infects Escherichia coli.
Arbitrium was first observed by a team led by Rotem Sorek, a microbial geneticist at the Weizmann Institute of Science in Israel. [2] [3] They were studying communication in Bacillus subtilis bacteria - in particular, how bacteria infected with phages warn nearby uninfected bacteria about the presence of these viruses.
