Mutations in the dimer interface of dihydrolipoamide dehydrogenase promote site-specific oxidative damages in yeast and human cells

J. Biol. Chem. jbc.M111.274415. First Published on September 19, 2011, doi:10.1074/jbc.M111.274415

DLD dimer interface mutations may accelerate frataxin turnover via an unknown mechanism

The role of DLD proteolytic activity remains unclear, and will require a better understanding of conditions that accelerate FXN turnover and the identification of additional natural substrates cleaved by DLD.
