Enzyme Information

2.7.7.6

DNA-directed RNA polymerase.

based on mapping to UniProt Q8RQE8

Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).

-!- Catalyzes 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 of alpha-amanitin, and the type of RNA synthesized. -!- See also EC 2.7.7.19 and EC 2.7.7.48.
