The P3 major capsid protein 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 [1].	Domain
