CC   -!- FUNCTION: Participates in transcription elongation, termination and
CC       antitermination. In the absence of Rho, increases the rate of
CC       transcription elongation by the RNA polymerase (RNAP), probably by
CC       partially suppressing pausing. In the presence of Rho, modulates most
CC       Rho-dependent termination events by interacting with the RNAP to render
CC       the complex more susceptible to the termination activity of Rho. May be
CC       required to overcome a kinetic limitation of Rho to function at certain
CC       terminators. Also involved in ribosomal RNA transcriptional
CC       antitermination. {ECO:0000255|HAMAP-Rule:MF_00948}.
CC   -!- SUBUNIT: Monomer. Interacts with the transcription termination factor
CC       Rho and with RNA polymerase. {ECO:0000255|HAMAP-Rule:MF_00948}.
CC   -!- SIMILARITY: Belongs to the NusG family. {ECO:0000255|HAMAP-
CC       Rule:MF_00948}.
