Function

[CAPSD_BPPRD] Major capsid protein self-assembles to form an icosahedral capsid with a pseudo T=25 symmetry, about 66 nm in diameter, and consisting of 240 capsid proteins trimers. The capsid encapsulates an inner membrane and the genomic dsDNA genome. The major coat protein P3 and two assembly factors (P10 and P17) are needed during the assembly of the virus particle inside the host cell, when the capsid protein multimers are capable of enclosing the host-derived membrane, containing the virus-encoded membrane-associated proteins.

Publication Abstract from PubMed

Bacteriophage PRD1 shares many structural and functional similarities with adenovirus. A major difference is the PRD1 internal membrane, which acts in concert with vertex proteins to translocate the phage genome into the host. Multiresolution models of the PRD1 capsid, together with genetic analyses, provide fine details of the molecular interactions associated with particle stability and membrane dynamics. The N- and C-termini of the major coat protein (P3), which are required for capsid assembly, act as conformational switches bridging capsid to membrane and linking P3 trimers. Electrostatic P3-membrane interactions increase virion stability upon DNA packaging. Newly revealed proteins suggest how the metastable vertex works and how the capsid edges are stabilized.
