|---|---|
| para | III tripara |
| TCIII | transcobalamin III |
| deoxyribonucleases, type III site-specific | <enzyme> Enzyme systems composed of two subunits and requiring ATP and magnesium for endonucleolytic activity; they do not function as atpases. They exist as complexes with modification methylases of similar specificity. The systems recognise specific short DNA sequences and cleave a short distance, about 24 to 27 bases, away from the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. Registry number: EC 3.1.21.5 (12 Dec 1998) |
|---|---|
| DNA polymerase III | <enzyme> An enzyme that aids in DNA replication. It has a number of different functions, such as: proofreading newly replicated DNA, removing nucleotides from the 3' end of the strand one by one, and binding nucleotides from the 5' end of the strand. (09 Oct 1997) |
| ductus pharyngobranchialis III | A narrow communication between the third branchial pouch and the pharynx in the embryo. (05 Mar 2000) |
| type III acrocephalosyndactyly | An autosomal dominant syndrome with variable expression of brachycephaly, maxillary hypoplasia, prominent ear crus, syndactyly, facial asymmetry, shallow orbits, telecanthus, and nasal septal deviation; may show mental retardation. Synonym: Saethre-Chotzen syndrome. (05 Mar 2000) |
| type III collagen | Collagen characteristic of reticular fibres. (05 Mar 2000) |
| type III familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by increased plasma levels of LDL, beta-lipoproteins, pre-beta-lipoproteins, cholesterol, phospholipids, and triglycerides; hypertriglyceridemia induced by a high carbohydrate diet, and glucose tolerance is abnormal; frequent eruptive xanthomas and atheromatosis, particularly coronary artery disease; biochemical defect lies in apolipoproteins; there are many varieties. Synonym: carbohydrate-induced hyperlipaemia, dysbetalipoproteinaemia, familial hyperbetalipoproteinaemia and hyperprebetalipoproteinaemia, familial hypercholesterolaemia with hyperlipaemia. (05 Mar 2000) |
| type III hyperlipoproteinaemia | <biochemistry> An inherited disorder (gene defect) where both cholesterol and triglycerides are elevated in the same patient. This condition accelerates the effects of atherosclerosis and thus increases the risk of cardiovascular disease. Conditions such as hypothyroidism, obesity and diabetes enhances this risk. Origin: Gr. Haima = blood (27 Sep 1997) |
| type III hypersensitivity reaction | An immunologic category of diseases evoked by the deposition of antigen-antibody or antigen-antibody-complement complexes on cell surfaces, with subsequent involvement of breakdown products of complement, platelets, and polymorphonuclear leukocytes, and development of vasculitis; nephritis is common. Arthus phenomenon and serum sickness are classic examples, but many other disorders, including most of the connective tissue disease's, may belong in this immunologic category; immune complex disease's can also occur during a variety of disease's of known aetiology, such as subacute bacterial endocarditis. See: autoimmune disease. Synonym: immune complex disorder, type III hypersensitivity reaction. (05 Mar 2000) |
| type III mucopolysaccharidosis | <syndrome> An error of the mucopolysaccharide metabolism, with excretion of large amounts of heparan sulfate in the urine and severe mental retardation with hepatomegaly; skeleton may be normal or may present mild changes similar to those in Hurler's syndrome; several different types (A, B, C, and D) have been identified according to the enzyme deficiency; autosomal recessive inheritance. Synonym: type III mucopolysaccharidosis. (05 Mar 2000) |
| exonuclease III | An exonuclease enzyme which removes nucleotides one at a time from the 5'-end of duplex DNA which does not have a phosphorylated 3'-end. (09 Oct 1997) |
| factor III | In the clotting of blood, tissue factor or thromboplastin; it initiates the extrinsic pathway by reacting with factor VII and calcium to form factor VIIa. See: thromboplastin. (05 Mar 2000) |
| uroporphyrin-III C-methyltransferase | <enzyme> From pseudomonas denitrificans; enzyme of the cobalamin biosynthetic pathway which catalyses the c methylation of uroporphyrinogen III; also catalyses both nad+ dependent oxidation of precorrin-2 to sirohydrochlorin and insertion of iron into it to produce siroheme; cysg gene is from E coli; product of coba gene of pseudomonas; do not confuse with coba gene product of salmonella typhimurium which yields ATP-corrinoid adenosyltransferase Registry number: EC 2.1.1.107 Synonym: uroiii methyltransferase, uroporphyrinogen III methylase, sumt methyltransferase, s-adenosylmethionine-uroporphyrinogen III methyltransferase, cysg gene product, siroheme synthase, coba gene product, propionibacterium (26 Jun 1999) |
| uroporphyrinogen-III synthase | <enzyme> An enzyme that catalyses the cyclization of hydroxymethylbilane to yield uroporphyrinogen III and water. Chemical name: Hydroxymethylbilane hydro-lyase (cyclizing) Registry number: EC 4.2.1.75 (12 Dec 1998) |
| forms of DNA i, II and III | Refers to circular DNA removed from viruses and as plasmids. Form I is the DNA in its normal, supercoiled form. Form II is the DNA after one of the two strands has been nicked (cut apart), and is circular. Form III is the DNA after both strands have been broken, and is linear. (09 Oct 1997) |
| Le Fort III craniofacial dysjunction | A complex fracture in which the facial bones are separated from the cranial bones. Synonym: Le Fort III craniofacial dysjunction, Le Fort III fracture, transverse facial fracture. (05 Mar 2000) |
