Any of various enzymes that bring about the breakdown of proteins into peptides or amino acids by hydrolysis. Pepsin is an example of a protease.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.protease - any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis
caspase - any of a group of proteases that mediate apoptosis
enzyme - any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
angiotensin converting enzyme, angiotensin-converting enzyme, ACE - proteolytic enzyme that converts angiotensin I into angiotensin II
plasminogen activator, urokinase - protease produced in the kidney that converts plasminogen to plasmin and so initiates fibrinolysis
renin - a proteolytic enzyme secreted by the kidneys; catalyzes the formation of angiotensin and thus affects blood pressure
