#protease__peptidase__proteinase__proteolytic_enzyme__proteolyticenzyme  any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis
  supertype:  #enzyme  any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
  subtype:  #caspase  any of a group of proteases that mediate apoptosis
  subtype:  #angiotensin_converting_enzyme  proteolytic enzyme that converts angiotensin I into angiotensin II
  subtype:  #plasminogen_activator__plasminogenactivator__urokinase  protease produced in the kidney that converts plasminogen to plasmin and so initiates fibrinolysis
  subtype:  #renin  a proteolytic enzyme secreted by the kidneys; catalyzes the formation of angiotensin and thus affects blood pressure
