[2Fe-2S] cluster transfer in iron-sulfur protein biogenesis.
Sesto Fiorentino, Italy. In Proc Natl Acad Sci U S A, 2014
Here we show that the structural plasticity of the dimeric state of the [2Fe-2S] bound form of human GRX5 (holo hGRX5) is the crucial factor that allows an efficient cluster transfer to the partner proteins human ISCA1 and ISCA2 by a specific protein-protein recognition mechanism.
