Asymmetric Unit(hide GO term definitions)
Chain A   (CAPSF_BPPH2 | B3VMP4)
biological process
    GO:0046718    viral entry into host cell    The process that occurs after viral attachment by which a virus, or viral nucleic acid, breaches the plasma membrane or cell envelope and enters the host cell. The process ends when the viral nucleic acid is released into the host cell cytoplasm.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
    GO:0019062    virion attachment to host cell    The process by which a virion protein binds to molecules on the host cellular surface or host cell surface projection.
cellular component
    GO:0098022    viral capsid, fiber    A type of capsid decoration composed of fiber structures.
    GO:0046729    viral procapsid    A stable empty viral capsid produced during the assembly of viruses.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
