| adenylate kinase | <enzyme> An enzyme that catalyses the phosphorylation of AMP to ADP in the presence of ATP or inorganic triphosphate. Chemical name: ATP:AMP phosphotransferase Registry number: EC 2.7.4.3 (12 Dec 1998) |
| aminoacyl adenylate | The product formed by the condensation of the acyl radical of an amino acid and adenosine 5'-monophosphate (originally in the form of adenosine 5'-triphosphate, with elimination of a pyrophosphoric group). Formed in the first step of protein biosynthesis. Synonym: activated amino acid. (05 Mar 2000) |
| nucleoside triphosphate-adenylate kinase | <enzyme> Other nucleoside triphosphates may replace GTP as substrate Registry number: EC 2.7.4.10 Synonym: GTP-AMP phosphotransferase, AMP-GTP phosphotransferase (26 Jun 1999) |
| luciferyl adenylate | An intermediate compound in the pathway of bioluminescence. Its precursor is the pigment luciferin. It is the substrate of the enzyme luciferase, which combines it with oxygen to make visible light. (09 Oct 1997) |
| abietadiene cyclase | <enzyme> Converts geranylgeranyl pyrophosphate to (-)-abieta-7(8),13(14)-diene; from lodgepole pine or grand fir Registry number: EC 5.- Synonym: abietadiene synthase (26 Jun 1999) |
| adenosine diphosphate ribose cyclase | <enzyme> Catalyses conversion of nadp to 2'-phospho-cyclic adenosine diphosphoribose; do not use for formation of cyclic adpribose (see ADP-ribosyl cyclase) Registry number: EC 4.6.- Synonym: 2'-p-adpr cyclase (26 Jun 1999) |
| adenyl cyclase | <enzyme> An enzyme that converts adenosine monophosphate to cyclic adenosine monophosphate, an intracellular second messenger of neural or hormonal activation. (05 Mar 2000) |
| adenylyl cyclase | The former name for adenylate cyclase. (05 Mar 2000) |
| aklanonic acid methyl ester cyclase | <enzyme> Catalyses the formation of aklaviketone from aklanonic acid methyl ester; involved in daunomycin biosynthesis; see also daunorubicin-doxorubicin polyketide synthase Registry number: EC 5.- Synonym: aame cyclase, daud protein, daud gene product, dnrd protein, dnrd gene product (26 Jun 1999) |
