Gene: [06p2/BCKDE1B] 2-oxoisovalerate dehydrogenase (lipoamide), beta polypeptide; branched chain keto acid dehydrogenase E1, beta polypeptide; maple syrup urine disease (due to BCK-E1-beta deficiency);

FAG

The branched-chain ketoacid dehydrogenase alpha subunit gene have been mapped to chromosome 19; see also GEM:19q132/BCKDE1A."

FUN

The holoenzyme functions as a component of multienzyme complex BCKD, which decarboxylates branched chain keto acids, adds them to coenzyme A, and synthesizes NADH."
