CC   -!- FUNCTION: Positively regulates expression of some phage genes.
CC       Bacterial host RNA polymerase modified by antitermination proteins
CC       transcribes through termination sites that otherwise prevent expression
CC       of the regulated genes (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the phage antitermination Q type 1 family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA84322.1; Type=Erroneous initiation; Evidence={ECO:0000305};
