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. |
Catalytic activity | RHEA:32271: (2R,3S)-3-isopropylmalate + NAD(+) = 4-methyl-2-oxopentanoate + CO2 + NADH
EC 1.1.1.85 |
Cofactor | Mg(2+) Mn(2+) Note: Binds 1 Mg(2+) or Mn(2+) ion per subunit. |
Pathway | Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine from 3-methyl-2-oxobutanoate: step 3/4. |
Subunit | Homodimer. |
Subcellular location | Cytoplasm. |
Similarity | Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 1 subfamily. |
