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) (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Acetyl-CoA + 3-methyl-2-oxobutanoate + H(2)O =
CC       (2S)-2-isopropylmalate + CoA.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-
CC       leucine from 3-methyl-2-oxobutanoate: step 1/4.
CC   -!- SUBUNIT: Homotetramer (By similarity).
CC   -!- SIMILARITY: Belongs to the alpha-IPM synthase/homocitrate synthase
CC       family. LeuA type 2 subfamily.
