CC   -!- FUNCTION: Global transcriptional regulator that plays a key role in
CC       stress response and exerts either positive or negative regulation of
CC       genes. Acts by interacting with the C-terminal domain of the alpha
CC       subunit of the RNA polymerase (RNAP). This interaction can enhance
CC       binding of RNAP to the promoter region of target genes and stimulate
CC       their transcription, or block interaction of RNAP with activator.
CC       {ECO:0000255|HAMAP-Rule:MF_01132}.
CC   -!- SUBUNIT: Interacts with the C-terminal domain of the alpha subunit of
CC       the RNAP. {ECO:0000255|HAMAP-Rule:MF_01132}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01132}.
CC   -!- SIMILARITY: Belongs to the ArsC family. Spx subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01132}.
