Protein

Pyruvate dehydrogenase E1 component subunit alpha-1, mitochondrial

Gene

E1 ALPHA

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2. It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3).

Catalytic activityi

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

Cofactori

Thiamine pyrophosphate.

Enzyme regulationi

E1 activity is regulated by phosphorylation (inactivation) and dephosphorylation (activation) of the alpha subunit.By similarity
