Regulation of mammalian pdc activity is accomplished in large part by phosphorylation (resulting in inactivation) of the e1 component by a family of pyruvate dehydrogenase kinases (pdk 14 isozymes) and dephosphorylation (leading to activation) of phosphorylated e1 by a set of specific phosphatases (phosphopyruvate dehydrogenase phosphatase 12 isozymes) (1, 3-6). The subunit of the e1 component has three phosphorylation sites, named site 1 (ser-264), site 2 (ser-271), and site 3 (ser-203), and phosphorylation of any one of these three sites results in inactivation |
