| 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) |

| DNA polymerase | <enzyme, molecular biology> Enzymes involved in template directed synthesis of DNA from deoxyribonucleotide triphosphates. I, II and III are known in E. Coli, III appears to be most important in genome replication and I is important for its ability to edit out unpaired bases at the end of growing strands. Animal cells have and polymerases, with apparently responsible for replication of nuclear DNA and for replication of mitochondrial. All these function with a DNA strand as template. Retroviruses possess a unique DNA polymerase (reverse transcriptase) that uses an RNA template. (18 Nov 1997) |
| DNA polymerase beta | <enzyme> A DNA repair enzyme that catalyses DNA synthesis during base excision DNA repair. Registry number: EC 2.7.7.- (12 Dec 1998) |
| DNA polymerase i | DNA Polymerase I is an enzyme that aids in DNA replication. It has the following 3 functions: 1. Polymerizes in the 5(r) to 3(r) direction on single-stranded template. 2. Degrades single or double-stranded DNA from a free 3(r)-OH end, and 3. Degrades double-stranded DNA from a free 5(r) end. (09 Oct 1997) |
| DNA polymerase II | <enzyme> An enzyme that aids in DNA replication. It has a number of different functions, including the repair of ultraviolet radiation damaged DNA. (09 Oct 1997) |
| DNA polymerase III | <enzyme> An enzyme that aids in DNA replication. It has a number of different functions, such as: proofreading newly replicated DNA, removing nucleotides from the 3' end of the strand one by one, and binding nucleotides from the 5' end of the strand. (09 Oct 1997) |
| DyNAzyme polymerase | <enzyme> Commercial product from finnzymes used for gene amplification Registry number: EC 2.7.7.- (26 Jun 1999) |

Flexneri, rfc gene product, o-antigen polymerase, shigella, o-antigen polymerase, pseudomonas, rfc protein, pseudomonas, o-antigen polymerase, e. Coli (26 Jun 1999) |
| Taq polymerase | <enzyme, molecular biology> A heat stable DNA polymerase that is normally used in the polymerase chain reaction. It was isolated from Thermobius aquaticus. (18 Nov 1997) |
| Tet DNA polymerase | <enzyme> From thermus thermophilus; thermostable, used as a replacement for taq polymerase in DNA sequencing Registry number: EC 2.7.7.- Synonym: DNA polymerase tet (26 Jun 1999) |
| Tli polymerase | <enzyme> Used in polymerase chain reactions; contains a 3'-5' proofreading exonuclease activity Registry number: EC 2.7.7.- Synonym: thermococcus litoralis DNA polymerase, vent, vent(exo-) DNA polymerase, vent(r) DNA polymerase (26 Jun 1999) |
| UlTma DNA polymerase | <enzyme> A thermostable DNA polymerase with putative proofreading activity Registry number: EC 2.7.7.- (26 Jun 1999) |
| A chain | A polypeptide component of insulin containing 21 amino acyl residues, beginning with a glycyl residue (NH2-terminus); insulin is formed by the linkage of an A chain to a B chain by two disulfide bonds; the amino-acid composition of the A chain is a function of species. Synonym: glycyl chain. In general, one of the polypeptides in a multiprotein complex. (05 Mar 2000) |
| alpha chain disease | A vague or indefinite term; could be used for alpha-heavy-chain disease (a lymphoplasma cell proliferative disease usually seen in Mediterranean men, characterised by intestinal involvement with steatorrhoea, often progressive with fatal outcome) or a thalassaemia (a genetic abnormality in the alpha globin chain of haemoglobin). (05 Mar 2000) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
