Abstract excerpt

Elucidating how proteins control the reduction potentials (E0') of [Fe--S] clusters is a longstanding fundamental problem in bioinorganic chemistry. Two site-directed variants of Azotobacter vinelandii ferredoxin I (FdI) that show large shifts in [Fe--S] cluster E0' (100--200 mV versus standard hydrogen electrode (SHE)) have been characterized. High resolution X-ray structures of F2H and F25H variants in their...
