CC   -!- FUNCTION: DNA helicase which seems to act as a postreplicative
CC       transcription termination factor. Involved in ATP-dependent
CC       release of nascent RNA. Forms a stable complex with single-
CC       stranded DNA, and to a lesser extent RNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with G2. Might be part of a transcription
CC       complex composed at least of G2, A18, and H5. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=Localizes to the
CC       virion core. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the helicase family. Poxviruses subfamily.
CC       {ECO:0000305}.
