Term Name: peptidase activity
Synonyms: hydrolase, acting on peptide bonds, peptidase activity, acting on D-amino acid peptides, peptidase activity, acting on L-amino acid peptides, peptide hydrolase activity, protease activity, proteinase activity
Definition: 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.
