Pyruvate dehydrogenase E1 component subunit alpha, somatic form, mitochondrial

Gene

PDHA1

Organism
Pan troglodytes (Chimpanzee)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript 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

Enzyme regulationi

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

Post-translational modificationi

Phosphorylation at Ser-232, Ser-293 and Ser-300 by PDK family kinases inactivates the enzyme; for this phosphorylation at a single site is sufficient. Phosphorylation at Ser-293 interferes with access to active site, and thereby inactivates the enzyme. Dephosphorylation at all three sites, i.e. at Ser-232, Ser-293 and Ser-300, is required for reactivation (By similarity).By similarity
Acetylation alters the phosphorylation pattern. Deacetylated by SIRT3 (By similarity).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
