CC   -!- FUNCTION: Involved in the catabolism of short chain fatty acids (SCFA)
CC       via the tricarboxylic acid (TCA)(acetyl degradation route) and via the
CC       2-methylcitrate cycle I (propionate degradation route). Catalyzes the
CC       dehydration of 2-methylcitrate (2-MC) to yield the cis isomer of 2-
CC       methyl-aconitate. Could also catalyze the dehydration of citrate and
CC       the hydration of cis-aconitate. {ECO:0000250|UniProtKB:P77243}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2S,3S)-2-methylcitrate = 2-methyl-cis-aconitate + H2O;
CC         Xref=Rhea:RHEA:17725, ChEBI:CHEBI:15377, ChEBI:CHEBI:57872,
CC         ChEBI:CHEBI:58853; EC=4.2.1.79;
CC         Evidence={ECO:0000250|UniProtKB:P77243};
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:P77243};
CC   -!- PATHWAY: Organic acid metabolism; propanoate degradation.
CC       {ECO:0000250|UniProtKB:P77243}.
CC   -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; isocitrate
CC       from oxaloacetate: step 2/2. {ECO:0000250|UniProtKB:P77243}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:P77243}.
CC   -!- SIMILARITY: Belongs to the PrpD family. {ECO:0000305}.
