General Information
Term poly(A) RNA polymerase activity ID (Ontology) GO:1990817 (Gene Ontology)
Definition Catalysis of the reaction: ATP + RNA(n) = diphosphate + RNA(n)-3'-adenine ribonucleotide. The primer may be an RNA or DNA fragment, or oligo(A) bearing a 3'-OH terminal group.[ PubMed:13965521 ]
Also Known As "polynucleotide adenylyltransferase activity" ; "RNA adenylating enzyme" ; "RNA adenyltransferase activity" (for all, see Synonyms field below)
