General annotation (Comments)

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 By similarity.

Catalytic activity

(2R,3S)-3-isopropylmalate + NAD+ = 4-methyl-2-oxopentanoate + CO2 + NADH. HAMAP MF_01033

Cofactor

Binds 1 magnesium or manganese ion per subunit By similarity.

Pathway

Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine from 3-methyl-2-oxobutanoate: step 3/4. HAMAP MF_01033

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 1 subfamily.
