| Ag-Ab | antigen-antibody complex |
| NADPH-cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
|---|---|
| succinate cytochrome c oxidoreductase | <enzyme> A portion of the electron transport chain, catalyzing the transfer of electrons from succinate to cytochrome c via fad, ubiquinone, and cytochrome b. The first step is catalyzed by succinate dehydrogenase (ec 1.3.99.1), the other steps are not well characterised. Registry number: EC 1.- (12 Dec 1998) |
| QH2 cytochrome C reductase | <enzyme> Membrane bound complex in the mitochondrial inner membrane, responsible for electron transfer from reduced coenzyme Q to cytochrome C. Contains cytochromes b and c1 and iron sulphur proteins. (18 Nov 1997) |
| triazole cytochrome P-450-obtusifoliol-14-demethylase | <enzyme> Key enzyme in plant sterol biosynthesis Registry number: EC 1.- Synonym: tcpo demethylase, obtusifoliol 14 alpha-methyl demethylase (26 Jun 1999) |
| ubiquinol-cytochrome-c reductase | <enzyme> An 11-subunit enzyme complex that acts as an electron transferring protein in the mitochondrial respiratory chain. The enzyme complex catalyses the oxidation of ubiquinol to ubiquinone and ferrocytochrome c in the presence of ferricytochrome c. It contains cytochromes b-562, b-566, and c1 as well as an iron ferredoxin. Chemical name: Ubiquinol-ferricytochrome-c oxidoreductase Registry number: EC 1.10.2.2 (12 Dec 1998) |
| aberrant complex | An anomalous electrocardiographic complex, more specifically an abnormal ventricular complex caused by abnormal intraventricular conduction of a supraventricular impulse. (05 Mar 2000) |
| activated complex | <chemistry> State of highest energy during a reaction. When reactants form the activated complex, bond breaking and bond formation is occurring. Synonym: transition state. (09 Jan 1998) |
| AIDS dementia complex | <immunology> A frequent cerebral condition in people with AIDS that results in the loss of cognitive capacity, affecting the ability to function in a social or occupational setting. Its cause has not been determined exactly, but may result from HIV infection of cells in the brain or an inflammatory reaction to such infection. (09 Oct 1997) |
| aids-related complex | A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating aids-related complex (arc) from aids include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in aids; follicular or mixed hyperplasia in arc lymph nodes, leading to lymphocyte degeneration and depletion more typical of aids; evolving succession of histopathological lesions such as localization of kaposi's sarcoma, signaling the transition to the full-blown aids. (12 Dec 1998) |
| alpha-keto acid dehydrogenase complex | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase.

| alpha-ketoglutarate dehydrogenase complex | alpha-ketoglutarate dehydrogenase |
| amygdaloid complex | Almond-shaped group of basal nuclei anterior to the inferior horn of the lateral ventricle of the brain, within the temporal lobe. The amygdala is part of the limbic system. (12 Dec 1998) |
| anomalous complex | A complex in the electrocardiogram differing significantly from the physiologic type in the same lead. (05 Mar 2000) |
| antennal complex | <cell biology> Light harvesting complexes (LHC) of protein and pigment in or on photosynthetic membranes of bacteria are organised into arrays, called antennae. They transfer photon energy to reaction centres. (18 Nov 1997) |
| antennapedia complex | A set of mutations that cause developmental defects in the limbs and appendages of the fruit fly Drosophila melanogaster, such as the development of legs (-pedia) in the places where antennae are supposed to be. (09 Oct 1997) |
