Bacteriophage M13, G5P, DNA-binding (IPR003512)

Short name: Phage_M13_G5P_DNA-bd

Overlapping homologous superfamilies

Family relationships



This entry is represented by the Bacteriophage M13, G5P, DNA-binding protein. The characteristics of the protein distribution suggest prophage matches in addition to the phage matches.

G5P is the bacteriophage helix-destabilising protein, or single-stranded DNA binding protein, required for DNA synthesis. The protein binds to DNA in a highly cooperative manner without pronounced sequence specificity. In the presence of single-stranded DNA it binds cooperatively to form a helical protein-DNA complex. It prevents the conversion during synthesis of the single-stranded (progeny) viral DNA back into the double-stranded replicative form.
