The activity of the BCKD complex, the rate-limiting enzyme in the BCAA catabolism, has clearly diminished.
The BCKD complex is composed of four subunits named E1a, E1[beta], E2, and E3, around a cubic core of 24 identical dihydrolipoyl transacylase subunits of E2, encoded by the DBT gene (10).
It presents at any age, depending on residual BCKD activity.
MSUD is caused by a deficiency of the BCKD gene complex, which catalyses the decarboxylation of the alphaketo acids of leucine, isoleucine, and valine to their respective branched-chain acyl-CoAs.
Specific BCKD activity was measured upon addition of 0.5 mM [alpha]-ketoisovalerate.
