Homologous Superfamily

Bacteriophage PRD1, P3, N-terminal (IPR016115)

Short name: Phage_PRD1_P3_N

Overlapping entries


The major capsid protein P3 from Bacteriophage PRD1 adopts a double-barrel structure comprising two eight-stranded viral beta-barrels or jelly rolls, each of which contains a 12-residue alpha-helix. This protein then trimerises through a 'trimerisation loop' sequence, and is incorporated within the viral capsid [PMID: 11752778].

This superfamily represents the N-terminal domain which has a distorted beta-sandwich topology.
