Capsid protein G8P

Gene

VIII

Organism
Enterobacteria phage fd (Bacteriophage fd)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Self assembles to form a helical capsid wrapping up the viral genomic DNA. The capsid displays a filamentous structure with a length of 760-1950 nm and a width of 6-8 nm. The virion assembly and budding take place at the host inner membrane (By similarity).By similarity
