Summary

Lipoic acid is a prosthetic group of the acyltransferase (E2) components of the pyruvate, (α-ketoglutarate, and branched chain α-keto acid dehydrogenase complexes, X component (the dihydrolipoamide dehydrogenase-binding protein) of the eucaryotic pyruvate dehydrogenase complex, and H-protein of the glycine cleavage system. The lipoyl moiety is attached in amide linkage to the ε-amino group of specific lysine residues of the proteins. Although the role of lipoic acid in these proteins has been well studied, intensive research on enzyme(s) concerning the lipoylation of proteins have not been undertaken until recently. In this chapter, we describe the recent development about the lipoylation of E2 component and H-protein as well as the historical view of the studies about lipoylation.
