CC   -!- FUNCTION: Catalyzes the condensation of the acetyl group of
CC       acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form
CC       3-carboxy-3-hydroxy-4-methylpentanoate (2-isopropylmalate).
CC       {ECO:0000255|HAMAP-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,

CC         EC=2.3.3.13; Evidence={ECO:0000255|HAMAP-Rule:MF_01025};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-
CC       leucine from 3-methyl-2-oxobutanoate: step 1/4.
CC       {ECO:0000255|HAMAP-Rule:MF_01025}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01025}.
CC   -!- SIMILARITY: Belongs to the alpha-IPM synthase/homocitrate synthase
CC       family. LeuA type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_01025}.
