UniProt functional annotation for B3VMP4

UniProt code: B3VMP4.

Organism: Bacillus phage phi29 (Bacteriophage phi-29).
Taxonomy: Viruses; Duplodnaviria; Heunggongvirae; Uroviricota; Caudoviricetes; Caudovirales; Podoviridae; Picovirinae; Salasvirus.
 
Function: Protein that forms the 55 capsid fibers. These fibers are not always present and may have been lost in some lab strains. They may enhance the attachment of the virions onto the host cell wall. {ECO:0000269|PubMed:409854}.
