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       Also required for regulation of fis expression. {ECO:0000255|HAMAP-
CC       Rule:MF_00926}.
CC   -!- SUBUNIT: Interacts directly with the RNA polymerase.
CC       {ECO:0000255|HAMAP-Rule:MF_00926}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00926}.
CC   -!- SIMILARITY: Belongs to the DksA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00926}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAN78672.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
