== Function ==
 +
[https://www.uniprot.org/uniprot/ACNB_ECOLI ACNB_ECOLI] Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. Also catalyzes the hydration of 2-methyl-cis-aconitate to yield (2R,3S)-2-methylisocitrate. The apo form of AcnB functions as a RNA-binding regulatory protein. During oxidative stress inactive AcnB apo-enzyme without iron sulfur clusters binds the acnB mRNA 3' UTRs (untranslated regions), stabilizes acnB mRNA and increases AcnB synthesis, thus mediating a post-transcriptional positive autoregulatory switch. AcnB also decreases the stability of the sodA transcript.<ref>PMID:10585860</ref> <ref>PMID:10589714</ref> <ref>PMID:11932448</ref> <ref>PMID:12473114</ref> <ref>PMID:15882410</ref> <ref>PMID:8000525</ref> <ref>PMID:8932712</ref>
