Function

function

Catalyzes the oxidation of 3-carboxy-2-hydroxy-4-methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2-oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Mn2+ (UniProtKB | Rhea| CHEBI:29035 )

Note: Binds 1 Mg2+ or Mn2+ ion per subunit.
Mn2+ (UniProtKB | Rhea| CHEBI:29035 )

Pathway

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