Function

function

Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-ketoisovalerate) to form 3-carboxy-3-hydroxy-4-methylpentanoate (2-isopropylmalate).

Caution

Could be the product of a pseudogene. It lacks about 130 C-terminal residues, which corresponds to the regulatory domain.

Catalytic activity

Cofactor

Mn2+ (UniProtKB | Rhea| CHEBI:29035 )

Pathway

Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine from 3-methyl-2-oxobutanoate: step 1/4.
