The P3 major capsid protein adopts a 'double-sandwich' structure comprising two eight-stranded viral beta-sandwich domains with jellyroll fold, each of which contains a 12-residue alpha-helix. This protein trimerises through a 'trimerisation loop' sequence, and is incorporated within the viral capsid [1]. This entry represents the C-terminal domain of the P3 protein.	Domain
