Noun
S: (n) activator ((biology) any agency bringing about activation; a molecule that increases the activity of an enzyme or a protein that increases the production of a gene product in DNA transcription)
S: (n) enzyme (any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions)
S: (n) adenosine deaminase, ADA (an enzyme found in mammals that can catalyze the deamination of adenosine into inosine and ammonia) "ADA deficiency can lead to one form of severe combined immunodeficiency disease"; "the gene encoding ADA was one of the earlier human genes to be isolated and cloned for study"
S: (n) amylase (any of a group of proteins found in saliva and pancreatic juice and parts of plants; help convert starch to sugar)
S: (n) thrombin (an enzyme that acts on fibrinogen in blood causing it to clot)
S: (n) rennin, chymosin (an enzyme that occurs in gastric juice; causes milk to coagulate)
S: (n) collagenase (any enzyme that catalyzes the hydrolysis of collagen and gelatin)
S: (n) complement (one of a series of enzymes in the blood serum that are part of the immune response)
S: (n) catalase (enzyme found in most plant and animal cells that functions as an oxidative catalyst; decomposes hydrogen peroxide into oxygen and water)
S: (n) cyclooxygenase, Cox (either of two related enzymes that control the production of prostaglandins and are blocked by aspirin)
S: (n) cyclooxygenase-1, Cox-1 (an enzyme that regulates prostaglandins that are important for the health of the stomach lining and kidneys) "an unfortunate side effect of NSAIDs is that they block Cox-1"
S: (n) cyclooxygenase-2, Cox-2 (an enzyme that makes prostaglandins that cause inflammation and pain and fever) "the beneficial effects of NSAIDs result from their ability to block Cox-2"

S: (n) histaminase (enzyme that acts as a catalyst in converting histidine to histamine)
S: (n) hyaluronidase, spreading factor, Hyazyme (an enzyme (trade name Hyazyme) that splits hyaluronic acid and so lowers its viscosity and increases the permeability of connective tissue and the absorption of fluids)
S: (n) isomerase (an enzyme that catalyzes its substrate to an isomeric form)
S: (n) kinase (an enzyme that catalyzes the conversion of a proenzyme to an active enzyme)
S: (n) lipase (an enzyme secreted in the digestive tract that catalyzes the breakdown of fats into individual fatty acids that can be absorbed into the bloodstream)

S: (n) nuclease (general term for enzymes that catalyze the hydrolysis of nucleic acid by cleaving chains of nucleotides into smaller units)
S: (n) endonuclease (a nuclease that cleaves nucleic acids at interior bonds and so produces fragments of various sizes)
S: (n) restriction endonuclease, restriction nuclease, restriction enzyme (any of the enzymes that cut nucleic acid at specific restriction sites and produce restriction fragments; obtained from bacteria (where they cripple viral invaders); used in recombinant DNA technology)
S: (n) exonuclease (a nuclease that releases one nucleotide at a time (serially) beginning at one of a nucleic acid)
S: (n) oxidase (any of the enzymes that catalyze biological oxidation)
S: (n) peroxidase (any of a group of enzymes (occurring especially in plant cells) that catalyze the oxidation of a compound by a peroxide)
S: (n) rennin, chymosin (an enzyme that occurs in gastric juice; causes milk to coagulate)
S: (n) secretase (a set of enzymes believed to snip pieces off a longer protein producing fragments of amyloid protein that bunch up and create amyloid protein plaques in brain tissue (the pathological hallmark of Alzheimer's))
S: (n) streptodornase (an enzyme produced by some hemolytic strains of streptococcus that dissolves fibrinous secretions from infections; used medicinally (often in combination with streptokinase))
S: (n) streptokinase (an enzyme produced by some strains of streptococcus that can liquefy blood clots by converting plasminogen to plasmin; used medicinally in some cases of myocardial infarction and pulmonary embolism)
