| alpha-amino-beta-ketoadipic acid | 2-Amino-3-oxo-1,6-hexanedioic acid;an intermediate of porphobilinogen synthesis formed by d-aminolevulinic acid synthase from succinyl-CoA and glycine; it rapidly decarboxylates to d-aminolevulinic acid. (05 Mar 2000) |

| alpha,beta-ketoalkene reductase | <enzyme> Nadh is much less effective than NADPH; catalyses the reduction of the carbon-carbon double bond of five membered ring cpds which have two conjugated carbonyl groups on both sides of a double bond Registry number: EC 1.3.1.- Synonym: n-ethylmaleimide reducing enzyme, NADPH-linked alpha,beta-ketoalkene double bond reductase, n-ethylmaleimide reductase (26 Jun 1999) |
| alpha-D-mannose-beta-1,2-N-acetylglucosaminyltransferase | <enzyme> Absolute specificity for terminal branched mannosyl residues of glycolipids Registry number: EC 2.4.1.- Synonym: udpgnac-1,2-magtransferase (26 Jun 1999) |

| amyloid beta-protein | A 4 kD protein, 39-43 amino acids long, expressed by a gene located on chromosome 21. It is the major protein subunit of the vascular and plaque amyloid filaments in individuals with alzheimer's disease and in aged individuals with trisomy 21 (down syndrome). The protein is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue. (12 Dec 1998) |
| amyloid beta-protein precursor | A precursor to the amyloid-beta protein (beta/a4). Alterations in the expression of the amyloid beta-protein precursor (abpp) gene, located on chromosome 21, plays a role in the development of the neuropathology common to both alzheimer disease and down syndrome. Abpp is associated with the extensive extracellular matrix secreted by neuronal cells. Upon cleavage, this precursor produces three proteins of varying amino acid lengths: 695, 751, and 770. The beta/a4 (695 amino acids) or beta-amyloid protein is the principal component of the extracellular amyloid in senile plaques found in alzheimer disease, down syndrome and, to a limited extent, in normal aging.

| androst-16-en-3 beta-ol sulfotransferase | <enzyme> A beta sulfotransferase Registry number: EC 2.8.2.- Synonym: aebo sulfotransferase (26 Jun 1999) |
| androsta-5,16-dien-3 beta-ol synthetase | <enzyme> Nadph- and o(2)-dependent; converts progesterone to 4,16-androstadien-3-one and converts pregnenolone to androstadienol Registry number: EC 1.- Synonym: pregnenolone side-chain cleavage enzyme, 5,16-androstadien-3 beta-ol synthetase, 5,16-androstadien-3-ol synthase, 4,16-androstadien-3-one synthesizing enzyme, 4,16-adien-3-one synthase, 4,16-ado synthase, delta(16)-c(19)-steroid synthetase, andien-beta-synthetase, 16-ene-synthetase (26 Jun 1999) |

| beta 2-microglobulin | An 11 kD protein associated with the outer membrane of many cells including lymphocytes. It is the small subunit of the MHC class I molecule. Association with beta 2-microglobulin is generally required for the transport of class I heavy chains from the endoplasmic reticulum to the cell surface. Beta 2-microglobulin is present in small amounts in serum, csf, and urine of normal people, and to a much greater degree in the urine and plasma of patients with tubular proteinaemia, renal failure, or kidney transplants.

| beta-adrenergic blocking agent | A class of drugs that compete with beta-adrenergic agonists for available receptor sites; some compete for both b1 and b2 receptors (e.g., propranolol) while others are primarily either b1 (e.g., metoprolol) or b2 blockers; used in the treatment of a variety of cardiovascular diseases where beta-adrenergic blockade is desirable. Synonym: beta-adrenergic receptor blocking agent, beta-adrenoreceptor antagonist, beta-blocker. (05 Mar 2000) |
