CC   -!- FUNCTION: Represses the transcription of fabB, involved in unsaturated
CC       fatty acid (UFA) biosynthesis. By controlling UFA production, FabR
CC       directly influences the physical properties of the membrane bilayer.
CC       {ECO:0000255|HAMAP-Rule:MF_01190}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01190}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01190}.
