Chain A (LCCA_LEUGE | P34034)

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.
