CC   -!- FUNCTION: Transcription regulator that activates transcription by
CC       stimulating RNA polymerase (RNAP) recycling in case of stress
CC       conditions such as supercoiled DNA or high salt concentrations.
CC       Probably acts by releasing the RNAP, when it is trapped or
CC       immobilized on tightly supercoiled DNA. Does not activate
CC       transcription on linear DNA. Probably not involved in DNA repair.
CC       {ECO:0000255|HAMAP-Rule:MF_01821}.
CC   -!- SUBUNIT: Interacts with the RNAP. Has a higher affinity for the
CC       core RNAP than for the holoenzyme. Its ATPase activity is
CC       stimulated by binding to RNAP. {ECO:0000255|HAMAP-Rule:MF_01821}.
CC   -!- SIMILARITY: Belongs to the SNF2/RAD54 helicase family. RapA
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01821}.
