CC   -!- FUNCTION: Involved in transcription antitermination. Required for
CC       transcription of ribosomal RNA (rRNA) genes. Binds specifically to the
CC       boxA antiterminator sequence of the ribosomal RNA (rrn) operons.
CC       {ECO:0000255|HAMAP-Rule:MF_00073}.
CC   -!- SIMILARITY: Belongs to the NusB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00073}.
