Protein

Dihydrolipoyllysine-residue acetyltransferase component of pyruvate dehydrogenase complex, mitochondrial

Gene

Dlat

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2, and thereby links the glycolytic pathway to the tricarboxylic cycle.

Catalytic activityi

Acetyl-CoA + enzyme N6-(dihydrolipoyl)lysine = CoA + enzyme N6-(S-acetyldihydrolipoyl)lysine.

Cofactori

(R)-lipoateNote: Binds 1 lipoyl cofactor covalently.

Involvement in diseasei

Primary biliary cirrhosis (PBC) is an autoimmune disease characterized by inflammatory obliteration of intra-hepatic bile duct, leading to liver cell damage and cirrhosis. The E2 component of pyruvate dehydrogenase complex is the autoantigen for PBC.

Interactioni

Subunit structurei

Part of the multimeric pyruvate dehydrogenase complex that contains multiple copies of pyruvate dehydrogenase (subunits PDH1A and PDHB, E1), dihydrolipoamide acetyltransferase (DLAT, E2) and lipoamide dehydrogenase (DLD, E3). These subunits are bound to an inner core composed of about 48 DLAT and 12 PDHX molecules. Interacts with PDK2 and PDK3. Interacts with SIRT4. Interacts with PDHB.By similarity
