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}.
