CC   -!- FUNCTION: DNA-dependent ATPase required for providing the needed energy
CC       to achieve the termination of early transcripts. Acts in concert with
CC       the RAP94 subunit of the virion RNA polymerase and the capping
CC       enzyme/VTF to catalyze release of UUUUUNU-containing nascent RNA from
CC       the elongation complex. NPH-I must bind ssDNA in order to exhibit
CC       ATPase activity (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-
CC         diphosphate + H(+) + phosphate; Xref=Rhea:RHEA:23680,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC         ChEBI:CHEBI:57930, ChEBI:CHEBI:61557; EC=3.6.1.15;
CC   -!- SUBUNIT: Monomer. Interacts (via C-terminus) with RAP94 (via N-
CC       terminus). Interacts with the cap-specific mRNA (nucleoside-2'-O-)-
CC       methyltransferase (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=Virion core enzyme.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the helicase family. NPH I subfamily.
CC       {ECO:0000305}.
