General description

In many organisms, the pyruvate dehydrogenase (PDH) complex catalyzes the overall, irreversible conversion of pyruvate to acetyl-CoA and CO2 in the aerobic pathway. This complex also serves as a key regulator for cardiac substrate selection. It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1 or PDHE1-A type I), dihydrolipoamide acetyltransferase (E2), and lipoamide dehydrogenase (E3). PDH is regulated by both pyruvate dehydrogenase kinase (PDK)-mediated phosphorylation and feedback inhibition.

Specificity

This antibody recognizes PDHE1-A type I phosphorylated at Ser293.
