CC -!- FUNCTION: Transcription factor that acts by binding directly to the RNA
CC polymerase (RNAP). Required for negative regulation of rRNA expression
CC and positive regulation of several amino acid biosynthesis promoters.
CC {ECO:0000256|HAMAP-Rule:MF_00926}.
CC -!- SUBUNIT: Interacts directly with the RNA polymerase.
CC {ECO:0000256|HAMAP-Rule:MF_00926}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00926}.
CC -!- SIMILARITY: Belongs to the DksA family. {ECO:0000256|HAMAP-
CC Rule:MF_00926}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PTD98241.1}.
