| familial lipoprotein lipase inhibitor | An inhibitor found in certain individuals that inhibits lipoprotein lipase resulting in accumulation of chylomicrons, VLDL, and triacylglycerols; similar in symptoms to familial lipoprotein lipase deficiency. (05 Mar 2000) |
| lipoprotein-associated coagulation inhibitor | Formerly known as anticonvertin; a protein that inhibits the extrinsic pathway of coagulation by binding to the tissue factor III-factor VII-Calcium-factor Xa complex. (05 Mar 2000) |
| lupus coagulation inhibitor | An antiphospholipid antibody found in association with systemic lupus erythematosus (lupus erythematosus, systemic), antiphospholipid syndrome, and in a variety of other diseases as well as in healthy individuals. In vitro, the antibody interferes with the conversion of prothrombin to thrombin and prolongs the partial thromboplastin time. In vivo, it exerts a procoagulant effect resulting in thrombosis mainly in the larger veins and arteries. It further causes obstetrical complications, including foetal death and spontaneous abortion, as well as a variety of haematologic and neurologic complications. (12 Dec 1998) |
| acetoacetyl-acyl carrier protein synthase | <enzyme> E coli enzyme, that catalyses condensation of malonyl-acyl carrier protein plus acetyl-acyl carrier protein; not inhibited by cerulenin Registry number: EC 2.3.1.- Synonym: acetoacetyl-acp synthase (26 Jun 1999) |
| acid soluble spore protein | <molecular biology> A DNA binding protein in the spores of some bacteria, thought to stabilise the DNA in an A configuration, so protecting it from cleavage by enzymes or UV light. (18 Nov 1997) |
| acute-phase protein | <haematology> These plasma proteins (in addition to fibrinogen) increase 25% or more in response to inflammation and injury are under direct control of interleukin-6 (IL-6) (hepatocyte-stimulating factor). Other proteins which increase are ceruloplasmin, C3 and C4 which increase 50% or more; alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin and fibrinogen (the major determinant of viscosity 1 ) which increase two- to fourfold; C-reactive protein (CRP) and serum amyloid A which increase several hundred-fold. Despite long-held clinical opinion to the contrary, available data indicate that neither ESR nor measurement of specific acute-phase reactants are useful in excluding underlying infection or inflammation regardless of the pretest probability. These proteins are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. They can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumour markers. See also: amyloid, c-reactive protein, erythrocyte sedimentation rate, viscosity. (25 Jun 1999) |
| acyl-(acyl-carrier-protein)-phospholipid acyltransferase | <enzyme> Catalyses the formation of phosphatidylethanolamine from acyl-acyl carrier protein and 2-acyl-sn-glycero-3-phosphoethanolamine Registry number: EC 2.3.1.40 Synonym: 2-acyl-gpe acyltransferase, 2-acylglycerophosphoethanolamine acyltransferase (26 Jun 1999) |
| acyl-(acyl-carrier-protein)-UDP-N-acetylglucosamine acyltransferase | <enzyme> E coli enzyme involved in lipid a biosynthesis; uses beta-hydroxymyristoyl-acyl carrier protein to form udp-3-monoacyl-n-acetylglucosamine; amino acid sequence given in second source Registry number: EC 2.3.1.129 Synonym: udp-aguatransferase, lpxa protein, udp-n-acetylglucosamine-3-acyltransferase, udp-n-acetylglucosamine 3-o-acyltransferase, udp-3-o-(r-3-hydroxymyristoyl)glucosamine-n-acyltransferase, lpxd protein, fira gene product, fira protein (26 Jun 1999) |
| acyl carrier protein | <protein> A small (77 peptides long) protein which binds six other enzymes involved in fatty acid synthesis. It was first isolated in E. Coli bacteria. (09 Oct 1997) |
| acyl carrier protein acylase | <enzyme> From E coli Registry number: EC 2.3.1.- Synonym: acp acylase (26 Jun 1999) |

| AKT1 protein kinase | <enzyme> Human homolog of v-akt oncogene product Registry number: EC 2.7.10.- Synonym: akt1 protein, human (26 Jun 1999) |
| AMP-activated protein kinase kinase | <enzyme> An endogenous kinase kinase; reactivates the inactive form of AMP-activated protein kinase (AMP-pk); phosphorylates the 63-kD subunit of AMP-pk Registry number: EC 2.7.1.- Synonym: AMP-pk reactivator, hmg CoA reductase kinase kinase (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) |
