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}.
