Systematic name:
nucleoside-triphosphate:RNA nucleotidyltransferase (DNA-directed)



Catalyses DNA-template-directed extension of the 3'- end of an RNA strand by one nucleotide at a time. Can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to α-amanitin, and the type of RNA synthesized. See also EC (polynucleotide adenyltransferase) and EC (RNA-directed RNA polymerase).
