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 -!- SUBUNIT: Monomer or homodimer; in equilibrium, with a preference for
CC the monomer. Dimerization may be employed to package NusB in an
CC inactive form until recruitment into antitermination complexes.
CC {ECO:0000269|PubMed:15279620}.
CC -!- SIMILARITY: Belongs to the NusB family. {ECO:0000255|HAMAP-
CC Rule:MF_00073, ECO:0000305}.
