RT "The protein capsid of filamentous bacteriophage PH75 from Thermus
RT thermophilus.";
RL J. Mol. Biol. 309:401-421(2001).
CC -!- FUNCTION: Self assembles to form a helical capsid wrapping up the viral
CC genomic DNA. The capsid displays a filamentous structure with a length
CC of 760-1950 nm and a width of 6-8 nm. The virion assembly and budding
CC take place at the host inner membrane (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homomultimerizes. There are several thousands of this protein
CC in the phage capsid (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host membrane; Single-pass
CC membrane protein. Note=prior to assembly, the major capsid protein is
CC found associated with the bacterial host inner membrane. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the inovirus capsid protein family.
CC {ECO:0000305}.
