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}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABE09970.1; Type=Erroneous initiation; Evidence={ECO:0000305};
