NMR Structure(hide GO term definitions)
Chain A,B   (MCJA_ECOLX | Q9X2V7)
biological process
    GO:0019835    cytolysis    The rupture of cell membranes and the loss of cytoplasm.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or 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.
