CC -!- FUNCTION: Involved in the catabolism of short chain fatty acids (SCFA)
CC via the tricarboxylic acid (TCA)(acetyl degradation route) and probably
CC the 2-methylcitrate cycle I (propionate degradation route). Catalyzes
CC the reversible isomerization of citrate to isocitrate via cis-
CC aconitate. Could catalyze the hydration of 2-methyl-cis-aconitate to
CC yield (2R,3S)-2-methylisocitrate. The apo form of AcnA functions as a
CC RNA-binding regulatory protein. {ECO:0000250|UniProtKB:P09339,
CC ECO:0000250|UniProtKB:Q8ZP52}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=citrate = D-threo-isocitrate; Xref=Rhea:RHEA:10336,
CC ChEBI:CHEBI:15562, ChEBI:CHEBI:16947; EC=4.2.1.3;
CC Evidence={ECO:0000250|UniProtKB:Q8ZP52};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,3R)-3-hydroxybutane-1,2,3-tricarboxylate = 2-methyl-cis-
CC aconitate + H2O; Xref=Rhea:RHEA:17941, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:57429, ChEBI:CHEBI:57872; EC=4.2.1.99;
CC Evidence={ECO:0000250|UniProtKB:Q8ZP52};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000250|UniProtKB:P09339};
CC Note=Binds 1 [4Fe-4S] cluster per subunit.
CC {ECO:0000250|UniProtKB:P09339};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; isocitrate
CC from oxaloacetate: step 2/2. {ECO:0000250|UniProtKB:Q8ZP52}.
CC -!- PATHWAY: Organic acid metabolism; propanoate degradation.
CC {ECO:0000250|UniProtKB:Q8ZP52}.
CC -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:P09339}.
CC -!- SIMILARITY: Belongs to the aconitase/IPM isomerase family.
CC {ECO:0000305}.
