PubMed Abstract: Glutamate dehydrogenase 3 from Candida albicans (CaGdh3) catalyzes the reversible oxidative deamination of l-glutamate, playing an important role in the yeast-to-hyphal transition of C. albicans. Here we report the crystal structures of CaGdh3 and its complex with α-ketoglutarate and NADPH. CaGdh3 exists as a hexamer, with each subunit containing two domains. The substrate and coenzyme bind in the cleft between the two domains and their binding induces a conformational change in CaGdh3. Our results will help to understand the catalytic mechanism of CaGdh3 and will provide a structural basis for the design of antifungal drugs targeting the CaGdh3 pathway.
