| nucleic acids, nucleotides, and nucleosides | Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges). (12 Dec 1998) |
|---|---|
| nucleotides | The basic building blocks of nucleic acids. They are made up of a nitrogen-containing purine or pyrimidine base linked to a sugar (ribose or deoxyribose) and a phosphate group. (14 Nov 1997) |
| deoxyadenine nucleotides | Adenine nucleotides which contain deoxyribose as the sugar moiety. (12 Dec 1998) |
| deoxycytosine nucleotides | Cytosine nucleotides which contain deoxyribose as the sugar moiety. (12 Dec 1998) |
| deoxyguanine nucleotides | Guanine nucleotides which contain deoxyribose as the sugar moiety. (12 Dec 1998) |
| deoxyuracil nucleotides | Uracil nucleotides which contain deoxyribose as the sugar moiety. (12 Dec 1998) |
| thymine nucleotides | Phosphate esters of thymidine in n-glycosidic linkage with ribose or deoxyribose, as occurs in nucleic acids. (12 Dec 1998) |
| uracil | <biochemistry> The pyrimidine base from which uridine is derived. (18 Nov 1997) |
| uracil-6-carboxylic acid | Intermediate in the de novo synthesis of pyrimidines. Linked glycosidically to ribose 5' phosphate, orotate forms the pyrimidine nucleotide orotidylate, that on decarboxylation at position 5 of the pyrimidine ring yields the major nucleotide uridylate (uridine 5' phosphate). (18 Nov 1997) |
| uracil dehydrogenase | An oxidoreductase catalyzing oxidation of uracil to barbituric acid; also oxidises thymine. Synonym: uracil oxidase. (05 Mar 2000) |
| uracil-DNA glycosidase | <enzyme> Catalyses hydrolysis of n-glycosidic bond of damaged nucleotide residues to give free uracil and partly depyrimidinated DNA of unaltered chain length; does not cleave phosphodiester bonds; a DNA repair enzyme Registry number: EC 3.2.2.- Synonym: ura-DNA glycosidase, uracil-DNA glycosylase, uracil n-glycosidase, ura-DNA glycosylase, uracil n-glycosylase (26 Jun 1999) |
| uracil mustard | <chemical> Nitrogen mustard derivative of uracil. It is a alkylating antineoplastic agent that is used in lymphatic malignancies, and causes mainly gastrointestinal and bone marrow damage. Pharmacological action: antineoplastic agent, alkylating. Chemical name: 2,4(1H,3H)-Pyrimidinedione, 5-(bis(2-chloroethyl)amino)- (12 Dec 1998) |
| uracil oxidase | An oxidoreductase catalyzing oxidation of uracil to barbituric acid; also oxidises thymine. Synonym: uracil oxidase. (05 Mar 2000) |
| uracil permease | <chemical> Mediates uptake of uracil in eucaryotic organisms; does not transport other natural pyrimidines such as cytosine, thymine or uridine Chemical name: permease, uracil Synonym: n 137 (26 Jun 1999) |
| uracil phosphoribosyltransferase | See: phosphoribosyltransferase. (05 Mar 2000) |
