En grupp enzymer som katalyserar DNA-mallstyrd förlängning av 3'-änden av en RNA-sträng med en nukleotid åt gången. De kan initiera en helt ny sträng. Hos eukaryoter har tre former av enzymet kunnat särskiljas utifrån känslighet för alfa-amanitin och den typ av RNA som syntetiseras. EC 2.7.7.6.
Enzymes that catalyze DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized. (From Enzyme Nomenclature, 1992).
