CC   -!- FUNCTION: Catalyzes the condensation of the acetyl group of acetyl-CoA
CC       with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3-
CC       hydroxy-4-methylpentanoate (2-isopropylmalate). {ECO:0000255|HAMAP-
CC       Rule:MF_00572}.
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:0000255|HAMAP-Rule:MF_00572};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC       from 3-methyl-2-oxobutanoate: step 1/4. {ECO:0000255|HAMAP-
CC       Rule:MF_00572}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00572}.
CC   -!- SIMILARITY: Belongs to the alpha-IPM synthase/homocitrate synthase
CC       family. LeuA type 2 subfamily. {ECO:0000255|HAMAP-Rule:MF_00572}.
