Reaction: nucleoside triphosphate + RNAn = diphosphate + RNAn+1
Other name(s): RNA nucleotidyltransferase (RNA-directed); RNA nucleotidyltransferase (RNA-directed); RNA-dependent ribonucleate nucleotidyltransferase; 3D polymerase; PB1 proteins; PB2 proteins; phage f2 replicase; polymerase L; Q-β replicase; phage f2 replicase; ribonucleic acid replicase; ribonucleic acid-dependent ribonucleate nucleotidyltransferase; ribonucleic acid-dependent ribonucleic acid polymerase; ribonucleic replicase; ribonucleic synthetase; RNA replicase; RNA synthetase; RNA transcriptase; RNA-dependent ribonucleate nucleotidyltransferase; RDRP; RNA-dependent RNA polymerase; RNA-dependent RNA replicase; transcriptase
Systematic name: nucleoside-triphosphate:RNA nucleotidyltransferase (RNA-directed)
Comments: Catalyses RNA-template-directed extension of the 3'- end of an RNA strand by one nucleotide at a time. Can initiate a chain de novo. See also EC 22.214.171.124 DNA-directed RNA polymerase.
