Bacteriophage p22 portal vertex formation in vivo.

Journal of molecular biology - 1 Feb 2002

Abstract excerpt

Bacteriophage with double-stranded, linear DNA genomes package DNA into pre-assembled icosahedral procapsids through a unique vertex. The packaging vertex contains an oligomeric ring of a portal protein that serves as a recognition site for the packaging enzymes, a conduit for DNA translocation, and the site of tail attachment. Previous studies have suggested that the portal protein of bacteriophage P22 is not...
