Protein

Pyruvate dehydrogenase E1 component subunit alpha, somatic form

Gene

PDHA1

Organism
Canis familiaris (Dog) (Canis lupus familiaris)
Status
Reviewed - Annotation score: 3 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.By similarity

Catalytic activityi

Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO2.

Cofactori

Thiamine pyrophosphate.

Enzyme regulationi

Pyruvate dehydrogenase activity is inhibited by phosphorylation of PDHA1; it is reactivated by dephosphorylation.By similarity

Interactioni

Subunit structurei

Heterotetramer of two PDHA1 and two PDHB subunits. The heterotetramer interacts with DLAT, and is part of the multimeric pyruvate dehydrogenase complex that contains multiple copies of pyruvate dehydrogenase (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 (By similarity).By similarity
