CC   -!- FUNCTION: Involved in both the tricarboxylic acid (TCA) and
CC       methylcitric acid cycles (PubMed:28956599). Has both 2-methylcitrate
CC       dehydratase and citrate dehydratase activities. Catalyzes the
CC       dehydration of 2-methylcitrate (2-MC) to yield 2-methyl-cis-aconitate,
CC       and the dehydration of citrate to yield cis-aconitate. Cannot form
CC       isocitrate. Uses either (2S,3R)- or (2R,3S)-2-methylcitrate
CC       (PubMed:28956599). {ECO:0000269|PubMed:28956599}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-methylcitrate = 2-methyl-cis-aconitate + H2O;
CC         Xref=Rhea:RHEA:57496, ChEBI:CHEBI:15377, ChEBI:CHEBI:15598,
CC         ChEBI:CHEBI:57872; Evidence={ECO:0000269|PubMed:28956599};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=citrate = cis-aconitate + H2O; Xref=Rhea:RHEA:10228,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:16383, ChEBI:CHEBI:16947;
CC         Evidence={ECO:0000269|PubMed:28956599};
CC   -!- DEVELOPMENTAL STAGE: Expressed in the mother cell at intermediate
CC       stages of sporulation under the control of the sigma-E factor.
CC       {ECO:0000269|PubMed:8759838}.
CC   -!- INDUCTION: Subject to catabolite repression.
CC       {ECO:0000269|PubMed:8759838}.
CC   -!- SIMILARITY: Belongs to the PrpD family. {ECO:0000305}.
