General Information
Term virion attachment to host cell pilus ID (Ontology) GO:0039666 (Gene Ontology)
Definition The process by which a virion attaches to a host cell by binding to a pilus on the host cell surface. Pili are retractile filaments that protrude from gram-negative bacteria. Filamentous viruses can attach to the pilus tip, whereas icosahedral viruses can attach to the pilus side.
Also Known As "pilus-adsorption protein"
