molecular function
    GO:0008234    cysteine-type peptidase activity    Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.
    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: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:0016757    transferase activity, transferring glycosyl groups    Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
biological process
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
    GO:0006508    proteolysis    The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
