Comments

FUNCTION: Serves two roles in transcription; it acts in concert with viral termination factor/capping enzyme to catalyze release of UUUUUNU-containing nascent RNA from the elongation complex, and it acts by itself as a polymerase elongation factor to facilitate readthrough of intrinsic pause sites (By similarity).
CATALYTIC ACTIVITY: NTP + H₂O = NDP + phosphate.
SIMILARITY: Belongs to the helicase family. NPH I subfamily.
SIMILARITY: Contains 1 helicase ATP-binding domain.
SIMILARITY: Contains 1 helicase C-terminal domain.
