'''Pyruvate dehydrogenase kinase''' (PDK) is part of the pyruvate dehydrogenase complex. This complex is located in the mitochondria and converts pyruvate to acetyl-CoA as part of the citric acid cycle. PDK phosphphorylates serine residues on pyruvate dehydrogenase using ATP. There are 4 isozymes of PDK. The isozymes differ in length, activity and phosphorylation sites<ref>PMID:11486000</ref>. | '''Pyruvate dehydrogenase kinase''' (PDK) is part of the pyruvate dehydrogenase complex.
