Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (Q9S3L6_LYSSH | Q9S3L6)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008233    peptidase activity    Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
    GO:0004252    serine-type endopeptidase activity    Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
    GO:0008236    serine-type peptidase activity    Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
biological process
    GO:0006508    proteolysis    The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
