| 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) |
| bacteriophage T7 induced DNA polymerase | <enzyme> Complex of two proteins, phage gene 5 protein and E coli thioredoxin Registry number: EC 2.7.7.- Synonym: t7 phage DNA polymerase, sequenase, t7 DNA polymerase, thermo sequenase (26 Jun 1999) |
| ribonucleotide polymerase | <enzyme> DNA-dependent Registry number: EC 2.7.7.- Synonym: oligonucleotide polymerase, decaribonucleotide polymerase (26 Jun 1999) |
| ribose polymerase | <enzyme> Enzyme that catalyses the attachment of ADP ribose units to various nuclear proteins. This post translational modification of proteins is dependent on DNA and appears to be involved in the regulation of various cellular processes such as differentiation, proliferation and transformation. (18 Nov 1997) |
| 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) |
| Pfu DNA polymerase | <enzyme> From pyrococcus furiosus; shows sequence homology with alpha-like DNA polymerases; amino acid sequence given in first source Registry number: EC 2.7.7.- Synonym: pfu polymerase (26 Jun 1999) |
| MIP1 DNA polymerase | <enzyme> From saccharomyces cerevisiae; has structural similarity with the E coli DNA polymerase i-type enzymes Registry number: EC 2.7.7.- Synonym: mip1 gene product (26 Jun 1999) |
