molecular function
    GO:0060241    lysozyme inhibitor activity    Stops, prevents or reduces the activity of a lysozyme, an enzyme that hydrolyses the beta- (1,4) glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in peptidoglycan.
biological process
    GO:0043086    negative regulation of catalytic activity    Any process that stops or reduces the activity of an enzyme.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
