3-isopropylmalate dehydrogenase (P04173)

Identification
Name3-isopropylmalate dehydrogenase
Synonyms
  • 3-IPM-DH
  • IMDH
  • Beta-IPM dehydrogenase
Gene NameLEU2
Enzyme Class
Biological Properties
General FunctionInvolved in magnesium ion binding
Specific FunctionCatalyzes 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
