RA Gilbert D.G.;
RL Submitted (OCT-2015) to the EMBL/GenBank/DDBJ databases.
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:0000256|HAMAP-Rule:MF_00073}.
CC -!- SIMILARITY: Belongs to the NusB family. {ECO:0000256|ARBA:ARBA00005952,
CC ECO:0000256|HAMAP-Rule:MF_00073}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KUL35160.1}.
