| 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) |
| androgen-dependent secretory protease | <enzyme> Glycoprotein from dog prostate; hydrolyzes arginine and lysine-containing amide and ester protease substrates Registry number: EC 3.4.99.- Synonym: ads-protease (26 Jun 1999) |
| 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) |
| ATP dependent 26S protease | <enzyme> Degrades proteins conjugated to ubiquitin; composed of cf-1,cf-2, and cf-3; cf-2 (also known as 240-kD proteasome inhibitor) is identical to aminolevulinic acid dehydratase Registry number: EC 3.4.99.- Synonym: 26s protease, 26 s proteasome complex, 26s proteasome (26 Jun 1999) |
