thromboxane
| receptors, thromboxane | Cell surface proteins that bind thromboxanes with high affinity and trigger intracellular changes influencing the behaviour of cells. at least a subset of thromboxane receptors act via the inositol phosphate and diacylglycerol second messenger systems. (12 Dec 1998) |

| prostaglandin endoperoxide thromboxane isomerase | <enzyme> Converts prostaglandin h2 to thromboxane b2 and 12l-hydroxy-5,8,10-heptadecatrienoic acid Registry number: EC 5.3.99.- Synonym: endoperoxide-tx isomerase, pg endoperoxide thromboxane isomerase (26 Jun 1999) |
| thromboxane | <biochemistry> Arachidonic acid metabolites produced by the action of thromboxane synthetase on prostaglandin cyclic endoperoxides. Thromboxane A2 (TxA2) is a potent inducer of platelet aggregation and release and although unstable, the activation of platelets leads to the further production of TxA2. Also causes arteriolar constriction. Another endoperoxide product, prostacyclin, has the opposite effects. (18 Nov 1997) |
| thromboxane a2 | <chemical> An unstable intermediate between the prostaglandin endoperoxides and thromboxane b2. The compound has a bicyclic oxaneoxetane structure. It is a potent inducer of platelet aggregation and causes vasoconstriction. It is the principal component of rabbit aorta contracting substance (rcs). Chemical name: Thromboxa-5,13-dien-1-oic acid, 9,11-epoxy-15-hydroxy-, (5Z,9alpha,11alpha,13E,15S)- (12 Dec 1998) |
| thromboxane-a synthase | <enzyme> An enzyme found predominantly in platelet microsomes. It catalyses the conversion of pgg(2) and pgh(2) (prostaglandin endoperoxides) to thromboxane a2. Chemical name: (5Z,13E)-(15S)-9alpha,11alpha-Epidioxy-15-hydroxyprosta-5,13-dienoate thromboxane-A(2)-isomerase Registry number: EC 5.3.99.5 (12 Dec 1998) |
| thromboxane b2 | <chemical> A stable, physiologically active compound formed in vivo from the prostaglandin endoperoxides. It is important in the platelet-release reaction (release of ADP and serotonin). Chemical name: Thromboxa-5,13-dien-1-oic acid, 9,11,15-trihydroxy-, (5Z,9alpha,13E,15S)- (12 Dec 1998) |
| thromboxane dehydrogenase | <enzyme> Converts thromboxane b2 to 11-dehydro-thromboxane b2, but not the reverse reaction; uses nad but not nadp as cofactor; only attacks the 11-hydroxy group of txb2 Registry number: EC 1.1.1.- Synonym: thromboxane b2 dehydrogenase, 11-hydroxythromboxane b2 dehydrogenase, 11-hydroxy-txb2 dehydrogenase (26 Jun 1999) |
| acetoacetyl-CoA synthetase | <enzyme> Catalyses the conversion of acetoacetate and CoA in the presence of ATP to yield AMP, pyrophosphate and acetoacetyl-CoA; the latter is the first intermediate in cholesterogenesis; also acts more slowly on l-3-hydroxybutanoate Registry number: EC 6.2.1.16 Synonym: acetoacetyl-CoA ligase, acetoacetate-CoA ligase, acetoacetyl-coenzyme a synthetase (26 Jun 1999) |
| acetyl-CoA synthetase | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
| acid cholesterol ester synthetase | <enzyme> Aortal enzyme, does not require exogenous ATP or CoA; reverse reaction of cholesterol esterase Registry number: EC 3.1.1.- Synonym: cholesterol ester synthetase (26 Jun 1999) |
| acyl-CoA synthetase | General term for enzymes that form acyl-CoA, now called ligases, specifically, long-chain fatty acid-CoA ligase. (05 Mar 2000) |
| acyl protein synthetase | <enzyme> Component of the fatty acid reductase complex of luminescent bacteria Registry number: EC 2.3.1.- Synonym: luxe gene product, fatty acyl-protein synthetase (26 Jun 1999) |
| aerobactin synthetase | <enzyme> Condenses 2 molecules of n-epsilon-acetyl-n-epsilon-hydroxylysine with citric acid to form aerobactin Registry number: EC 4.1.3.- (26 Jun 1999) |
| alamethicin synthetase | <enzyme> ATP-dependent, similar to gramicidin s synthesis Registry number: EC 6.3.2.- (26 Jun 1999) |
| alpha-aminoadipyl-cysteinyl-valine synthetase | <enzyme> As of 9/27/95 this has been separated from isopenicillin n synthetase Registry number: EC 6.3.2.- Synonym: acv synthetase, aa-cysteine synthetase, delta-(alpha-aminoadipyl)-cys-val synthetase, delta-(l-alpha-aminoadipyl)-l-cyteinyl-d-valine synthetase, pcbab gene product, acva gene product (26 Jun 1999) |
