| beta-D-fucosidase | <enzyme> Catalyses hydrolysis of terminal non-reducing beta-d-fucose residues in beta-d-fucosides; also hydrolyzes beta-d-galactosides Registry number: EC 3.2.1.38 Synonym: beta-d-fucoside fucohydrolase (26 Jun 1999) |
| beta-d-galactosidase | A sugar-splitting enzyme that catalyses the hydrolysis of lactose into d-glucose and d-galactose, and that of other beta-d-galactosides; it also catalyses galactotransferase reactions; a deficiency of beta-d -galactosidase leads to problems in the intestinal digestion of lactose; used in the production of milk products for adults who do not have the intestinal enzyme; a defect of one isozyme of beta-d-galactosidase is associated with Morquio's syndrome type B. Compare: lactase persistence, lactase restriction. Synonym: lactase. (05 Mar 2000) |
| beta-D-galactoside alpha 2-6-sialyltransferase | <enzyme> Catalyses the reaction of cmp-n-acetylneuraminate and galactosylglycoprotein to yield cmp and n-acetylneuraminylgalactosylglycoprotein; cd75 and cd75w antigen were removed as sys - it is not equivalent to the enzyme. Registry number: EC 2.4.99.1 Synonym: cmp-n-acetylneuraminate-d-galactosyl-glycoprotein n-acetylneurainyltransferase, cmp-n-acetylneuraminate-beta-galactoside alpha-2,6-sialyltransferase, beta-galactosyl(1-4)n-acetylglucosaminide alpha(2-6)-sialyltransferase, gal-glcnac(2-6)-sialyltransferase, cmp-n-acetylneuraminic acid-lactose sialytransferase, cmp-acetylneuraminate galactoside (alpha 2-6)-sialyltransferase, cmp-n-acetylneuraminate-galactosylglycoprotein sialyltransferase, alpha 2-6-sialyltransferase, cmp-sialic acid-n-acetyllactosaminide alpha (2-6)-sialyltransferase, cmp-neuac-galactoside (alpha 2-6)-sialyltransferase, gal-1-4-glcnac alpha(2-6)-sialyltransferase, siat-1, beta-galctoside alpha2,6-sialyltransferase (26 Jun 1999) |
| beta-d-glucosidase | A glucohydrolase similar to alpha-d-glucosidase, but attacking beta-glucosides and releasing beta-d-glucose. Synonym: amygdalase, cellobiase, gentiobiase. (05 Mar 2000) |
| beta-d-glucuronidase | <enzyme> An enzyme catalyzing the hydrolysis of various beta-d-glucuronides, liberating free d-glucuronic acid and an alcohol; a deficiency of this enzyme is associated with Sly syndrome. Synonym: glusulase, glycuronidase. (05 Mar 2000) |
| beta-d-glucuronidase deficiency | A rare deficiency of beta-d-glucuronidase; an autosomal recessive disorder with several allelic forms, characterised by abnormal mucopolysaccharide metabolism leading to progressive mental deterioration, splenic and hepatic enlargement, and dysostosis multiplex. Synonym: mucopolysaccharidase. (05 Mar 2000) |
| beta-D-mannosidase | <enzyme> Catalyses hydrolysis of terminal, non-reducing beta-d-mannose residues in beta-d-mannosides Registry number: EC 3.2.1.25 Synonym: mannanase, beta-mannosidase, mana gene product (26 Jun 1999) |
| beta-DNA | <molecular biology> The normal form of DNA found in organisms, which exists as a right-handed helix. (09 Oct 1997) |
| beta-d thalassaemia | Thalassaemia due to a gene that depresses synthesis of both beta-and d-globin chains by the chromosome bearing the abnormal gene. Heterozygous state: thalassaemia minor with Hb F comprising 5 to 30% of total haemoglobin but distributed unevenly among cells, Hb A2 reduced or normal. Homozygous state: moderate anaemia with only Hb F present, no Hb A or Hb A2. Synonym: F thalassaemia. (05 Mar 2000) |
| beta emission | <radiobiology> Form of nuclear decay where a neutron splits into a proton plus electron plus neutrino set. The proton stays in the nucleus but the electron (beta ray) is ejected. (09 Oct 1997) |
| beta-endorphin | <chemical> A peptide consisting of amino acid sequence 61-91 of the endogenous pituitary hormone beta-lipotropin. The first four amino acids show a common tetrapeptide sequence with methionine- and leucine enkephalin. The compound shows opiate-like activity. Injection of beta-endorphin induces a profound analgesia of the whole body for several hours. This action is reversed after administration of naloxone. Chemical name: beta-Endorphin (12 Dec 1998) |
| beta error | The statistical error (said to be of the second kind or type II) made in testing when it is concluded that something is negative when it really is positive. Beta error is often referred to as a false negative. (12 Dec 1998) |
