protease

protease
See also peptidase. The term is normally reserved for endopeptidases that have very broad specificity and will cleave most proteins into small fragments. These are usually the digestive enzymes, eg. trypsin, pepsin etc., or enzymes of plant origin (eg. ficin, papain) or bacterial origin (eg. pronase, proteinase K). Proteases are widely used for peptide mapping and for structural studies.
