Chain A   (HLGB_STAAU | P0A077)
biological process
    GO:0019835    cytolysis    The rupture of cell membranes and the loss of cytoplasm.
    GO:0051715    cytolysis in other organism    The killing by an organism of a cell in another organism by means of the rupture of cell membranes and the loss of cytoplasm.
    GO:0044179    hemolysis in other organism    The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another.
    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.
