RL Submitted (AUG-2007) to the EMBL/GenBank/DDBJ databases.
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}.
