| malate ATP lyase | <chemical> Composed of malyl-CoA synthetase (EC 6.2.1.9) and malyl-CoA lyase (EC 4.3.24) Synonym: malate lyase (26 Jun 1999) |
|---|---|
| phosphoenolpyruvate carboxykinase (ATP) | <enzyme> An enzyme of the lyase class that catalyses the conversion of ATP and oxaloacetate to ADP, phosphoenolpyruvate, and carbon dioxide. The enzyme is found in some bacteria, yeast, and trypanosoma, and is important for the photosynthetic assimilation of carbon dioxide in some plants. Chemical name: ATP:oxaloacetate carboxy-lyase (transphosphorylating) Registry number: EC 4.1.1.49 (12 Dec 1998) |
| seryl-tRNA-ATP phosphotransferase | <enzyme> Produces phosphoseryl trna; plays suppressor role in in vitro globin synthesis Registry number: EC 2.7.1.- Synonym: ser-trna ptase, seryl trna kinase (26 Jun 1999) |
| hydrogen-transporting ATP synthase | <enzyme> A group of enzymes which are involved in the reversible synthesis of ATP and that transport protons from the cytoplasmic to the matrix side of the mitochondrial membrane. The flow of protons through the f(0) channel results in ATP synthesis by f1. Chemical name: ATP phosphohydrolase (H+-transporting) Registry number: EC 3.6.1.34 (12 Dec 1998) |
| DNA topoisomerase (ATP-hydrolysing) | <enzyme> An ATP-requiring enzyme which, in the presence of magnesium ions, introduces negative supertwists into closed and possibly linear duplex DNA. The enzyme is implicated in DNA replication and transcription. It causes the storage of mechanical strain energy in the superhelical turns of DNA at the expense of ATP hydrolysis. Chemical name: DNA topoisomerase (ATP-hydrolysing) Registry number: EC 5.99.1.3 (12 Dec 1998) |
| oligophosphoglyceroyl-ATP 3'-phosphodiesterase | <enzyme> Located in mitochondrial fraction of rat liver; selectively hydrolyzes the oligo cpd to monomeric units of 3-phosphoglyceroyl-gamma-triphospho-5'-adenosine Registry number: EC 3.1.4.- Synonym: opg-ATP-phosphodiesterase (26 Jun 1999) |
| aid to families with dependent children | Financial assistance provided by the government to indigent families with dependent children who meet certain requirements as defined by the social security act, title IV, in the u.s. (12 Dec 1998) |
| antibody-dependent cell cytotoxicity | The phenomenon of antibody-mediated target cell destruction by non-sensitised effector cells. The identity of the target cell varies, but it must possess surface IgG whose fc portion is intact. The effector cell is a "killer" cell possessing fc receptors. It may be a lymphocyte lacking conventional b- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent. (12 Dec 1998) |
| antibody-dependent enhancement | Enhancement of viral infectivity caused by non-neutralizing antibodies. There are at least two mechanisms known to account for this: mediation by fc receptors (receptors, fc) or by complement receptors (receptors, complement). Either the virus is complexed with antiviral IgG and binds to fc receptors, or virus is coated with antiviral IgM and binds to complement receptors. (12 Dec 1998) |
| aromatic NADH-dependent nitroreductase | <enzyme> See also record for 1-nitroreductase; type I nitroreductase is not inhibited by oxygen Registry number: EC 1.- Synonym: nitrofuran reductase, nitrofurazone reductase, type I nitroreductases, NADH-dependent nitro reductase, nitrofurantoin reductase, p-dinitrobenzene reductase, benznidazole nitroreductase, nifurtimox nitroreductase, oxygen-insensitive NADPH nitroreductase, nitrobenzene nitroreductase (26 Jun 1999) |
| aspartic acid 2-oxoglutarate-dependent dioxygenase | <enzyme> Hydroxylates one aspartic acid residue in the first egf-like unit of factor ix Registry number: EC 1.14.11.- Synonym: aspartate 2-oxoglutarate dioxygenase, asp-2-og-dioxygenase, aspartyl beta-hydroxylase, aspartyl (asparaginyl) beta-hydroxylase (26 Jun 1999) |
| autophosphorylation-dependent multifunctional protein kinase | <enzyme> A camp/ca(2+)-independent protein kinase; phosphorylates and activates phosphorylase b kinase; phosphorylates and inactivates glycogen synthase Registry number: EC 2.7.1.- Synonym: auto-kinase (26 Jun 1999) |
| calcium-calmodulin-dependent phosphodiesterase | <enzyme> Hydrolyzes both cgmp and camp; induced during mitogenesis Registry number: EC 3.1.4.- Synonym: ca-cam-phosphodiesterase, calmodulin-dependent cgmp phosphodiesterase (26 Jun 1999) |
| calcium-calmodulin dependent protein kinase | <enzyme> A calmodulin-dependent enzyme that catalyses the phosphorylation of proteins. This enzyme is also sometimes dependent on calcium. A wide range of proteins can act as acceptor, including vimentin, synapsin, glycogen synthase, myosin light chains, and the microtubule-associated proteins. Registry number: EC 2.7.10.- (12 Dec 1998) |
| calcium-dependent protein kinase | <enzyme> Mw 51,000; requires ca; not stimulated by calmodulin, phospholipids or diacylglycerol; phosphorylates casein and histones forming primarily phosphoserine and phosphothreonine, respectively Registry number: EC 2.7.1.- Synonym: paramecium ca-dependent protein kinase (26 Jun 1999) |
