CC -!- FUNCTION: Catalyzes the formation of succinate and glyoxylate from
CC isocitrate, a key step of the glyoxylate cycle, which operates as an
CC anaplerotic route for replenishing the tricarboxylic acid cycle.
CC Required for growth on ethanol or acetate, but dispensable when
CC fermentable carbon sources are available. Acts also on 2-
CC methylisocitrate. {ECO:0000256|ARBA:ARBA00037423}.
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|ARBA:ARBA00001050};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-threo-isocitrate = glyoxylate + succinate;
CC Xref=Rhea:RHEA:13245, ChEBI:CHEBI:15562, ChEBI:CHEBI:30031,
CC ChEBI:CHEBI:36655; EC=4.1.3.1;
CC Evidence={ECO:0000256|ARBA:ARBA00023531};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|PIRSR:PIRSR001362-3};
CC Note=Can also use Mn(2+) ion. {ECO:0000256|PIRSR:PIRSR001362-3};
CC -!- PATHWAY: Carbohydrate metabolism; glyoxylate cycle; (S)-malate from
CC isocitrate: step 1/2. {ECO:0000256|ARBA:ARBA00004793}.
CC -!- SIMILARITY: Belongs to the isocitrate lyase/PEP mutase superfamily.
CC Isocitrate lyase family. {ECO:0000256|ARBA:ARBA00005704,
CC ECO:0000256|PIRNR:PIRNR001362}.
