Function
Binds the promoter region of at least fabA and fabB, but probably not yqfA (PubMed:11160901, PubMed:19854834, PubMed:21276098). Represses the transcription of fabA and fabB, involved in unsaturated fatty acid (UFA) biosynthesis (PubMed:11859088). By controlling UFA production, FabR directly influences the physical properties of the membrane bilayer.
