| leupeptin acid reductase | <enzyme> Converts leupeptin acid (acetyl-l-leu-l-leu-l-arg) into leupeptin (acetyl-l-leu-l-leu-l-arginal); requires ATP and NADPH Registry number: EC 1.2.1.- (26 Jun 1999) |
|---|---|
| lipoamide reductase | <enzyme> An enzyme oxidizing dihydrolipoamide at the expense of NAD+; completes the oxidative decarboxylation of pyruvate; a part of several enzyme complexes (e.g., alpha-ketoglutarate dehydrogenase complex). Decreased activity leads to neuronal loss in brain resulting in psychomotor retardation. Synonym: coenzyme factor, lipoamide dehydrogenase, lipoamide reductase (NADH), lipoyl dehydrogenase.

| 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) |
