| analogue | <chemistry> A compound that is structurally similar to another. (10 Jan 1998) |

| base analogue | <biochemistry> A chemical which resembles a nucleotide base. They can substitute the Purine and pyrimidine bases that normally appear in DNA, despite minor differences in structure. May be used for inducing mutations, including point mutations. For example: 5 bromouracil can replace thymine or 2 aminopurine replace adenine. (13 Nov 1997) |
| nucleoside analogue | A synthetic molecule that resembles a naturally occuring nucleoside, but that lacks a bond site needed to link it to an adjacent nucleotide. (09 Oct 1997) |
| 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 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) |
| pyrimidine analogue |
a structural analogue of one of the pyrimidine bases (cytosine, thymine, or uracil): 5-fluorouracil and cytarabine (cytosine arabinoside), analogues of the cytosine nucleotide deoxycytidine, are important antineoplastic agents.
