CC -!- FUNCTION: Catalyzes the condensation of the acetyl group of acetyl-CoA
CC with 3-methyl-2-oxobutanoate (2-ketoisovalerate) to form 3-carboxy-3-
CC hydroxy-4-methylpentanoate (2-isopropylmalate). {ECO:0000256|HAMAP-
CC Rule:MF_01025}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-methyl-2-oxobutanoate + acetyl-CoA + H2O = (2S)-2-
CC isopropylmalate + CoA + H(+); Xref=Rhea:RHEA:21524, ChEBI:CHEBI:1178,
CC ChEBI:CHEBI:11851, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.3.13;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01025};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01025};
CC -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC from 3-methyl-2-oxobutanoate: step 1/4. {ECO:0000256|ARBA:ARBA00004689,
CC ECO:0000256|HAMAP-Rule:MF_01025}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01025}.
CC -!- SIMILARITY: Belongs to the alpha-IPM synthase/homocitrate synthase
CC family. LeuA type 1 subfamily. {ECO:0000256|ARBA:ARBA00009396,
CC ECO:0000256|HAMAP-Rule:MF_01025}.
