Asymmetric Unit(hide GO term definitions)
Chain A,B   (HBP2_RHIAP | O77421)
molecular function
    GO:0043176    amine binding    Interacting selectively and non-covalently with any organic compound that is weakly basic in character and contains an amino or a substituted amino group.
biological process
    GO:0030682    evasion or tolerance of host defense response    Any process, either active or passive, by which an organism avoids or tolerates the effects of its host organism's defense response. The host defense response is mounted by the host in response to the presence of the organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
