| 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) |
|---|---|
| nucleosides | Purine or pyrimidine bases attached to a ribose or deoxyribose. (12 Dec 1998) |
| pyrimidine | <biochemistry> A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They are planar and aromatic in character and include several nucleic acid constituents (cytosine, thymine, and uracil) and form the basic structure of the barbiturates. It is the parent compound of the pyrimidine bases of nucleic acid. (21 Jun 2000) |
| pyrimidine-5'-nucleotide nucleosidase | <enzyme> Also acts on some deoxyribonucleotides Registry number: EC 3.2.2.10 Synonym: pyr-5'-nt-nucleosidase (26 Jun 1999) |
| pyrimidine(6-4)pyrimidone photolyase | <enzyme> Catalyses the light-dependent repair of pyrimidine(6-4)pyrimidone photoproducts; shows 20-22% sequence identity with class I cpd photolyase; genbank d83701 (drosophila), d83702 (human) Registry number: EC 4.1.99.- Synonym: (6-4)photolyase (26 Jun 1999) |
| pyrimidine base | <biochemistry> A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They are planar and aromatic in character and include several nucleic acid constituents (cytosine, thymine, and uracil) and form the basic structure of the barbiturates. It is the parent compound of the pyrimidine bases of nucleic acid. (21 Jun 2000) |
| pyrimidine deoxyribonucleoside kinase | <enzyme> Consider also thymidine kinase (EC 2.7.1.21) or deoxycytidine kinase (EC 2.7.1.74) Registry number: EC 2.7.- Synonym: pyrimidine drn kinase (26 Jun 1999) |
| pyrimidine dimer | <biochemistry> A dimer product found in DNA chains damaged by ultraviolet irradiation. Most frequently thymidine dimers. They consist of two adjacent pyrimidine nucleotides, usually thymine nucleotides, in which the pyrimidine residues are covalently joined by a cyclobutane ring. These dimers stop DNA replication. (21 Jun 2000) |
| pyrimidine-guanine sequence-specific ribonuclease | <enzyme> From yolk granules of adult rana catesbeiana oocytes Registry number: EC 3.1.27.- Synonym: rc-rnase, rana catesbeiana rnase (26 Jun 1999) |
| pyrimidine-nucleoside phosphorylase | <enzyme> Consider uridine phosphorylase and thymidine phosphorylase Registry number: EC 2.4.2.2 Synonym: pyrimidine nucleoside phosphorylase (26 Jun 1999) |
| pyrimidine phosphoribosyltransferase | <enzyme> Pyrimidine monophosphate and pyrophosphate gives pyrimidine and phosphoribosyl pyrophosphate; acts with uracil, orotic acid or fluorouracil Registry number: EC 2.4.2.- (26 Jun 1999) |
| pyrimidine transferase | <enzyme> An enzyme catalyzing transfer of a pyridine or other bases into the position of the pyrimidine in thiamin; e.g., thiamin reacting with pyridine produces heteropyrithiamin and 4-methyl-5-(2'-hydroxyethyl)-thiazole. Synonym: pyrimidine transferase, thiaminase I. (05 Mar 2000) |
