Restriction Enzyme: From 2 Different Sources
An endonuclease ENZYME, extracted from BACTERIA, that is used to cut DNA into short segments – a process essential in GENETIC ENGINEERING.
(restriction endonuclease) an enzyme, obtained from bacteria, that cuts DNA into specific short segments. Restriction enzymes are widely used in *genetic engineering.
Usually a protein made by the body to make chemical reactions take place at a faster rate or to cause a colour change in a laboratory test.... enzyme
This is a sensitive method for measuring the quantity of a substance. An antibody to the substance is prepared along with an ENZYME which binds to the antibody and which can be accurately measured using colour changes that occur as a result of the chemical reaction.... enzyme-linked immunosorbent assay (elisa)
An enzyme is a substance produced in the body, acting as a catalyst to trigger chemical change in another. Complex substances are thereby broken down into simple compounds to facilitate assimilation and absorption, as in the digestive juices. ... enzymes
A substance that converts angiotensin I to its active form, angiotensin. Drugs that reduce the action of this enzyme are known as ACE inhibitor drugs and are used in the treatment of hypertension and heart failure.... angiotensin converting enzyme
(ELISA) a sensitive technique for measuring the amount of a substance. An antibody that will bind to the substance is produced; the amount of an easily measured enzyme that then binds to the antibody complex enables accurate measurement.... enzyme-linked immunosorbent assay
see intrauterine growth restriction.... fetal growth restriction
(IUGR, fetal growth restriction) failure of a fetus to achieve its growth potential, resulting in the birth of a baby whose birth weight is abnormally low in relation to its gestational age (see small for gestational age). Causes include *uteroplacental insufficiency, maternal disease (e.g. infection, malnutrition, high blood pressure, smoking, and alcoholism), poor socioeconomic conditions, multiple pregnancy (e.g. twins), and fetal disease or chromosomal abnormalities. It may be associated with *preterm birth.... intrauterine growth restriction
(PERT) a therapeutic approach using supplements of the digestive enzymes lipase, amylase, and protease (Creon, Pancrex), which are given when there is insufficient endogenous production of pancreatic enzymes: for example, to patients with pancreatic cancer or cystic fibrosis. The capsules must be taken with all meals and snacks to be effective. PERT treats the symptoms of *steatorrhoea.... pancreatic enzyme replacement therapy
a digestive enzyme that causes the breakdown of protein. See endopeptidase; exopeptidase.... proteolytic enzyme
