Protein

Lipoamide acyltransferase component of branched-chain alpha-keto acid dehydrogenase complex, mitochondrial

Gene

Dbt

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

The branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO2. It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3). Within this complex, the catalytic function of this enzyme is to accept, and to transfer to coenzyme A, acyl groups that are generated by the branched-chain alpha-keto acid decarboxylase component.

Catalytic activityi

2-methylpropanoyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)-(S-(2-methylpropanoyl)dihydrolipoyl)lysine.

Cofactori

Binds 1 lipoyl cofactor covalently.By similarity
