General Information

General Information Comment Organism
physiological function in vivo the T4 phage packaging motor deals with Y- or X-structures in the replicative concatemer substrate by employing a portal-bound Holliday junction resolvase that trims and releases these DNA roadblocks to packaging. Purified T4 gp49 endonuclease VII resolvase can release DNA compression in vitro in prohead portal packaging motor anchored and arrested Y-DNA substrates. Conformational changes in both the motor proteins and the DNA substrate itself that are associated with the power stroke of the motor are consistent with a proposed linear motor employing a terminal-to-portal DNA grip-and-release mechanism Tequatrovirus T4
