| polynucleotide ligases | <enzyme> Catalyze the joining of preformed ribonucleotides or deoxyribonucleotides in phosphodiester linkage during genetic processes. Registry number: EC 6.5.1. (12 Dec 1998) |

| polynucleotide | <molecular biology> Linear sequences of nucleotides, in which the 5' linked phosphate on one sugar group is covalently linked to the 3' position on the adjacent sugars. In the polynucleotide DNA the sugar is deoxyribose and in RNA, ribose. They may be double stranded or single stranded with varying amounts of internal folding. (14 Oct 1997) |

| polynucleotide 5'-phosphatase | <enzyme> Chemical name: 5'-polynucleotidase Registry number: EC 3.1.3.33 (26 Jun 1999) |
| polynucleotide adenylyltransferase | <enzyme> An enzyme that catalyses the synthesis of polyadenylic acid from ATP. May be due to the action of RNA polymerase (ec 2.7.7.6) or polynucleotide adenylyltransferase (ec 2.7.7.19). Chemical name: ATP:polynucleotide adenylyltransferase Registry number: EC 2.7.7.19 (12 Dec 1998) |
| polynucleotide methylases | Enzymes that catalyze the methylation of purine and/or pyrimidine bases of polynucleotides, or of the sugars of polynucleotides. Synonym: polynucleotide methylases. (05 Mar 2000) |
| polynucleotide methyltransferases | Enzymes that catalyze the methylation of purine and/or pyrimidine bases of polynucleotides, or of the sugars of polynucleotides. Synonym: polynucleotide methylases. (05 Mar 2000) |
| polynucleotide phosphorylase | <enzyme> An enzyme of the transferase class that catalyses the reaction RNA(n+1) and orthophosphate to yield RNA(n) and a nucleoside diphosphate, or the reverse reaction. ADP, idp, GDP, udp, and cdp can act as donors in the latter case. Chemical name: Polyribonucleotide:orthophosphate nucleotidyltransferase Registry number: EC 2.7.7.8 (12 Dec 1998) |
| polynucleotide thioltransferases | Enzymes that catalyze specific thiolation reaction of purine and/or pyrimidine bases in polynucleotides. (05 Mar 2000) |
| 100RNP-polynucleotide phosphorylase | <enzyme> A chloroplast exoribonuclease that degrades polyadenylated RNA much faster than non-polyadenylated RNA Registry number: EC 3.1.13.- Synonym: 100rnp-pnpase (26 Jun 1999) |
| aminoacid-tRNA ligases | Recommended name for aminoacyl-tRNA synthetases, e.g., tyrosine-tRNA ligase for tyrosyl-tRNA synthetase. (05 Mar 2000) |
| amino acyl-tRNA ligases | <enzyme> Any of the group of ligases that catalyses the ATP-driven formation of a bond between an amino acid and a trna, activating the amino acids as a step in protein synthesis. Individual enzymes are highly specific for one amino acid and for any trna corresponding to that amino acid. Registry number: EC 6.1.1. (12 Dec 1998) |
| carbon-carbon ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-carbon bond. These are the carboxylating enzymes and are mostly biotinyl-proteins. Registry number: EC 6.4 (12 Dec 1998) |
| carbon-nitrogen ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-nitrogen bond. Registry number: EC 6.3 (12 Dec 1998) |
| carbon-nitrogen ligases with glutamine as amide-n-donor | <enzyme> Enzymes that catalyze the joining of glutamine-derived ammonia and another molecule. The linkage is in the form of a carbon-nitrogen bond. Registry number: EC 6.3.5 (12 Dec 1998) |
