CC -!- FUNCTION: Catalyzes the thermodynamically favored C-C bond cleavage of
CC (2R,3S)-2-methylisocitrate to yield pyruvate and succinate.
CC {ECO:0000256|RuleBase:RU361121}.
CC -!- FUNCTION: Involved in the catabolism of short chain fatty acids (SCFA)
CC via the 2-methylcitrate cycle (propionate degradation route). Catalyzes
CC the thermodynamically favored C-C bond cleavage of (2R,3S)-2-
CC methylisocitrate to yield pyruvate and succinate via an alpha-carboxy-
CC carbanion intermediate. {ECO:0000256|HAMAP-Rule:MF_01939}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S,3R)-3-hydroxybutane-1,2,3-tricarboxylate = pyruvate +
CC succinate; Xref=Rhea:RHEA:16809, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:30031, ChEBI:CHEBI:57429; EC=4.1.3.30;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01939,
CC ECO:0000256|RuleBase:RU361121};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|HAMAP-Rule:MF_01939};
CC -!- PATHWAY: Organic acid metabolism; propanoate degradation.
CC {ECO:0000256|HAMAP-Rule:MF_01939, ECO:0000256|RuleBase:RU361121}.
CC -!- SUBUNIT: Homotetramer; dimer of dimers. {ECO:0000256|HAMAP-
CC Rule:MF_01939}.
CC -!- SIMILARITY: Belongs to the isocitrate lyase/PEP mutase superfamily.
CC Methylisocitrate lyase family. {ECO:0000256|ARBA:ARBA00009282,
CC ECO:0000256|HAMAP-Rule:MF_01939, ECO:0000256|RuleBase:RU361121}.
