cysteine-type endopeptidase activity
Catalysis of the hydrolysis of internal, alpha-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.
The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
acid phosphatase activity
Catalysis of the reaction: an orthophosphoric monoester + H2O = an alcohol + phosphate, with an acid pH optimum.
