| polyribonucleotide nucleotidyltransferase | <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) |

| polyribonucleotides | A group of 13 or more ribonucleotides in which the phosphate residues of each ribonucleotide act as bridges in forming diester linkages between the ribose moieties. (12 Dec 1998) |
| 5'-phosphate-polyribonucleotide kinase | <enzyme> In presence of ATP and mg++ catalyses conversion of 5'-phosphate and 5'-diphosphate termini of RNA to 5'-triphosphate Registry number: EC 2.7.4.- (26 Jun 1999) |
