The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
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).
