RT "Genome sequence of Hahella sp. CCB-MM4 and discovery of its potential
RT applications.";
RL Submitted (DEC-2016) to the EMBL/GenBank/DDBJ databases.
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:0000256|HAMAP-
CC 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:OZG70049.1}.
