Asymmetric Unit(hide GO term definitions)
Chain A,B,C   (ELTB_CLOPF | P01558)
biological process
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
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.
