| adenylyl imidodiphosphate | <chemical> 5'-adenylic acid, monoanhydride with imidodiphosphoric acid. An analog of ATP, in which the oxygen atom bridging the beta to the gamma phosphate is replaced by a nitrogen atom. It is a potent competitive inhibitor of soluble and membrane-bound mitochondrial atpase and also inhibits ATP-dependent reactions of oxidative phosphorylation. Chemical name: 5'-Adenylic acid, monoanhydride with imidodiphosphoric acid (12 Dec 1998) |

| adenylyl sulfate-ammonia adenylyltransferase | <enzyme> Forms adenosine 5'-phosphoramidate Registry number: EC 2.7.7.- Synonym: adenylyl sulphate-ammonia adenylyltransferase, as-aat (26 Jun 1999) |
| adenylylosuccinate lyase | <enzyme> An enzyme that, in the course of purine ribonucleotide biosynthesis, catalyses the conversion of 5'-phosphoribosyl-4-(n-succinocarboxamide)-5-aminoimidazole to 5'-phosphoribosyl-4-carboxamide-5-aminoimidazole and the conversion of adenylosuccinic acid to AMP. Chemical name: N(6)-(1,2-Dicarboxyethyl)AMP AMP-lyase Registry number: EC 4.3.2.2 (12 Dec 1998) |
| adenylylosuccinate synthase | <enzyme> A carbon-nitrogen ligase. During purine ribonucleotide biosynthesis, this enzyme catalyses the synthesis of adenylosuccinate from GTP, imp, and aspartate with the formation of orthophosphate and GDP. Chemical name: IMP:L-aspartate ligase (GDP-forming) Registry number: EC 6.3.4.4 (12 Dec 1998) |
| adenylylosuccinic acid | A condensation product of aspartic acid and inosine 5'-monophosphate; an intermediate in the biosynthesis of adenylic acid. Formally, it is adenylic acid with succinic acid replacing an H of the NH2 group, forming a C-N. Synonym: adenylylosuccinic acid, N-succinyladenylic acid. Acronym: sAMP (05 Mar 2000) |
| adenylylsulfate kinase | adenosine 5'-phosphosulfate kinase |
