Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (IOVO_COTJA | P01003)
molecular function
    GO:0030414    peptidase inhibitor activity    Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds.
    GO:0004867    serine-type endopeptidase inhibitor activity    Stops, prevents or reduces the activity of serine-type endopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain; a serine residue (and a histidine residue) are at the active center of the enzyme.
biological process
    GO:0010951    negative regulation of endopeptidase activity    Any process that decreases the frequency, rate or extent of endopeptidase activity, the endohydrolysis of peptide bonds within proteins.
    GO:0010466    negative regulation of peptidase activity    Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.
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.
