CC -!- FUNCTION: Catalyzes the isomerization between 2-isopropylmalate and 3-
CC isopropylmalate, via the formation of 2-isopropylmaleate.
CC {ECO:0000255|HAMAP-Rule:MF_01027}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2R,3S)-3-isopropylmalate = (2S)-2-isopropylmalate;
CC Xref=Rhea:RHEA:32287, ChEBI:CHEBI:1178, ChEBI:CHEBI:35121;
CC EC=4.2.1.33; Evidence={ECO:0000255|HAMAP-Rule:MF_01027};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01027};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01027};
CC -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC from 3-methyl-2-oxobutanoate: step 2/4. {ECO:0000255|HAMAP-
CC Rule:MF_01027}.
CC -!- SUBUNIT: Heterodimer of LeuC and LeuD. {ECO:0000255|HAMAP-
CC Rule:MF_01027}.
CC -!- SIMILARITY: Belongs to the aconitase/IPM isomerase family. LeuC type 2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01027}.
