| flavin nucleotide | <biochemistry> Flavin derivatives that act as prosthetic groups (covalently linked cofactors) for flavin enzymes. (18 Nov 1997) |
|---|---|
| adenine | <biochemistry> A nitrogenous base, one member of the basepair A-T (thymine). (10 May 1997) |
| adenine arabinoside | Misnomer for arabinosyladenine. (05 Mar 2000) |
| adenine deaminase | <enzyme> An enzyme that catalyses the hydrolysis of adenine to ammonia and hypoxanthine. A part of purine degradation. (05 Mar 2000) |
| adenine deoxyribonucleotide | Deoxyadenosine monophosphate, a hydrolysis product of DNA, differing from adenylic acid in containing deoxyribose in place of ribose. Synonym: adenine deoxyribonucleotide. (05 Mar 2000) |
| adenine nucleotide | A condensation product of adenosine and phosphoric acid; a nucleotide found among the hydrolysis products of all nucleic acids. 3'-Adenylic acid (adenosine 3'-monophosphate) and 5'-adenylic acid (adenosine 5'-monophosphate) differ in the place of attachment of the phosphoric acid to the d-ribose; deoxyadenylic acid differs in having H instead of OH at the 2' position of d-ribose. See: AMP. Synonym: adenine nucleotide. (05 Mar 2000) |
| adenine nucleotide translocase | <enzyme> Catalyses the exchange between endogenous and exogenous adenine nucleotides in mitochondria.ec 2.7.7.-. Registry number: EC 2.7.7.- (12 Dec 1998) |
| adenine phosphoribosyltransferase | <enzyme> An enzyme catalyzing the formation of AMP from adenine and phosphoribosylpyrophosphate. It can act as a salvage enzyme for recycling of adenine into nucleic acids. Chemical name: AMP:pyrophosphate phospho-D-ribosyltransferase Registry number: EC 2.4.2.7 (12 Dec 1998) |
| adenine sulfate | Adenine conjugated with sulfuric acid; used to stimulate leukocyte production in agranulocytosis. (05 Mar 2000) |
| mRNA(adenine-N6)-methyltransferase | <enzyme> Methylates mRNA at internal adenosine within the consensus sequence puac(a/c/u) Registry number: EC 2.1.1.- Synonym: mRNA-a-n6-methyltransferase, mRNA(adenine-n6)-methylase (26 Jun 1999) |
| site-specific DNA-methyltransferase (adenine-specific) | <enzyme> An enzyme responsible for producing a species-characteristic methylation pattern on adenine residues in a specific short base sequence in the host cell DNA. The enzyme catalyses the methylation of DNA adenine in the presence of s-adenosyl-l-methionine to form DNA containing 6-methylaminopurine and s-adenosyl-l-homocysteine. Registry number: EC 2.1.1.72 (12 Dec 1998) |
