Summary
In this review the structure and function of the lipoamide dehydrogenase component of the keto acid dehydrogenase complexes is discussed. Three structural models are available and in recent years many new genes have been sequenced and expressed. Unsolved is the role that many non-complex-bound lipoamide dehydrogenases play in metabolism and the physiological function of free lipoic acid. Central in catalysis is the problem of stabilization of the 2-electron reduced enzyme. Mutagenesis studies and the use of a modified flavin cofactor revealed the various factors involved in this stabilization in which also the core component of the complex has a function.
