CC -!- FUNCTION: Participates in both transcription termination and
CC antitermination. {ECO:0000256|HAMAP-Rule:MF_00945}.
CC -!- SUBUNIT: Monomer. Binds directly to the core enzyme of the DNA-
CC dependent RNA polymerase and to nascent RNA. {ECO:0000256|HAMAP-
CC Rule:MF_00945}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00945}.
CC -!- SIMILARITY: Belongs to the NusA family. {ECO:0000256|HAMAP-
CC Rule:MF_00945}.
