Proteins, 80:661-666, 2012 Cited by PubMed Abstract: Homoisocitrate dehydrogenase (HICDH) catalyzes the conversion of homoisocitrate to 2-oxoadipate, the third enzymatic step in the α-aminoadipate pathway by which lysine is synthesized in fungi and certain archaebacteria. This enzyme represents a potential target for anti-fungal drug design. Here, we describe the first crystal structures of a fungal HICDH, including structures of an apoenzyme and a binary complex with a glycine tri-peptide. The structures illustrate the homology of HICDH with other β-hydroxyacid oxidative decarboxylases and reveal key differences with the active site of Thermus thermophilus HICDH that provide insights into the differences in substrate specificity of these enzymes.
