| bacteriophage T3 RNA polymerase | <enzyme> Used for the rapid generation of strand-specific RNA molecules that can be used for the identification of genes in hybridization experiments Registry number: EC 2.7.7.- Synonym: t3 RNA polymerase (26 Jun 1999) |
|---|---|
| RNA-directed DNA polymerase | <enzyme> An enzyme that synthesises DNA on an RNA template. It is encoded by the pol gene of retroviruses and by certain retrovirus-like elements. Chemical name: Deoxynucleotide-triphosphate:DNA deoxynucleotidyltransferase (RNA-directed) Registry number: EC 2.7.7.49 (12 Dec 1998) |
| RNA polymerase | <enzyme, molecular biology> An enzyme that polymerise ribonucleotides in accordance with the information present in DNA. Prokaryotes have a single enzyme for the three RNA types that is subject to stringent regulatory mechanisms. Eukaryotes have type I that synthesises all rRNA except the 5S component, type II that synthesises mRNA and hnRNA and type III that synthesises tRNA and the 5S component of rRNA. (23 Aug 1998) |
| RNA polymerase I | <enzyme> A DNA-dependent RNA polymerase present in bacterial, plant, and animal cells. The enzyme functions in the nucleolar structure and transcribes DNA into RNA. It has different requirements for cations and salts than RNA polymerase II and III and is not inhibited by alpha-amanitin. Registry number: EC 2.7.7.- (12 Dec 1998) |
| RNA polymerase II | <enzyme> A DNA-dependent RNA polymerase present in bacterial, plant, and animal cells. It functions in the nucleoplasmic structure and transcribes DNA into RNA. It has different requirements for cations and salt than RNA polymerase I and is strongly inhibited by alpha-amanitin. Registry number: EC 2.7.7.- (12 Dec 1998) |
| RNA polymerase III | <enzyme> A DNA-dependent RNA polymerase present in bacterial, plant, and animal cells. It functions in the nucleoplasmic structure where it transcribes DNA into RNA. It has specific requirements for cations and salt and has shown an intermediate sensitivity to alpha-amanitin in comparison to RNA polymerase I and II. Registry number: EC 2.7.7.- (12 Dec 1998) |
| polymerase, DNA or RNA | Enzymes that catalyse the synthesis of nucleic acids on pre-existing nucleic acid templates, assembling RNA from ribonucleotides or DNA from deoxyribonucleotides. (05 Mar 2000) |
| polymerase, RNA | Enzyme that catalyses (speeds) the polymerization of RNA. Rna polymerase uses preexisting nucleic acid templates and assembles the RNA from ribonucleotides. (12 Dec 1998) |
| DNA-directed RNA polymerase | <enzyme> A group of enzymes that catalyses DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesised. Chemical name: Nucleoside-triphosphate:RNA nucleotidyltransferase (DNA-directed) Registry number: EC 2.7.7.6 (12 Dec 1998) |
| receptors, sigma | A class of cell surface receptors recognised by its pharmacological profile. Sigma receptors were originally considered to be opioid receptors because they bind certain synthetic opioids. However they also interact with a variety of other psychoactive drugs, and their endogenous ligand is not known (although they can react to certain endogenous steroids). Sigma receptors are found in the immune, endocrine, and nervous systems, and in some peripheral tissues. (12 Dec 1998) |
| sigma | The 18th letter of the Greek alphabet, σ. (05 Mar 2000) |
| sigma bond | <chemistry> A bond formed from the overlap of either two s-orbitals or two hybrid orbitals such as sp3 or sp2 orbitals. (09 Jan 1998) |
| sigma effect | The decrease in apparent viscosity that occurs when a suspension, such as blood, is made to flow through a tube of smaller diameter; observed in tubes less than about 0.3 mm in diameter. Synonym: sigma effect. (05 Mar 2000) |
| sigma factor | Initiation factor (86 kD) that binds to E. Coli DNA dependent RNA polymerase and promotes attachment to specific initiation sites on DNA. Following attachment, the sigma factor is released. (18 Nov 1997) |
| sigma peptide | A peptide with one end bonded to a point within the chain, usually by means of the disulfide group of a cystine residue, so that only one end of the peptide is free; so called since the peptide chain has then the rough shape of the Greek letter sigma; e.g., oxytocin. (05 Mar 2000) |
