CC   -!- FUNCTION: Protein that forms the 55 capsid fibers. These fibers are not
CC       always present and may have been lost in some lab strains. They may
CC       enhance the attachment of the virions onto the host cell wall.
CC       {ECO:0000250|UniProtKB:B3VMP4}.
CC   -!- SUBUNIT: Homotrimer. Forms a super helix coiled coil in the homotrimer.
CC       {ECO:0000250|UniProtKB:B3VMP4}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:B3VMP4}.
CC   -!- SIMILARITY: Belongs to the phi29likevirus major capsid fiber protein
CC       family. {ECO:0000305}.
