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 immobilized
CC       on tightly supercoiled DNA. Does not activate transcription on linear
CC       DNA. Probably not involved in DNA repair. {ECO:0000255|HAMAP-
CC       Rule:MF_01821}.
CC   -!- SUBUNIT: Interacts with the RNAP. Has a higher affinity for the core
CC       RNAP than for the holoenzyme. Its ATPase activity is stimulated by
CC       binding to RNAP. {ECO:0000255|HAMAP-Rule:MF_01821}.
CC   -!- SIMILARITY: Belongs to the SNF2/RAD54 helicase family. RapA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01821}.
