RNA polymerase I activity

Term ID

GO:0001054

Synonyms

• DNA-directed RNA polymerase activity involved in transcription from RNA polymerase I promoter

Definition

Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains an RNA polymerase I specific promoter to direct initiation and 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'.
