== Function ==
[https://www.uniprot.org/uniprot/DLDH_YEAST DLDH_YEAST] Lipoamide dehydrogenase is a component of the alpha-ketoacid dehydrogenase complexes. This includes the pyruvate dehydrogenase complex, which catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). Acts also as component of the glycine cleavage system (glycine decarboxylase complex), which catalyzes the degradation of glycine.

== Publication Abstract from PubMed ==
The crystal structure of eucaryotic lipoamide dehydrogenase from yeast has been determined by an X-ray analysis at 2.7 (partially at 2.4) A resolution. The enzyme has two identical subunits related by a pseudo twofold symmetry. The tertiary structure is similar to those of other procaryotic enzymes. The active site, consisting of FAD, Cys44, and Cys49 from one subunit and His457' from the other subunit, is highly conserved. This enzyme is directly bound to the core protein E2 of the 2-oxoglutarate dehydrogenase complex, whereas it is bound to the pyruvate dehydrogenase complex through a protein X. The calculated electrostatic potential suggests two characteristic regions for binding with these two proteins.
