| 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) |
