Neutron crystallographic analyses at near‐atomic resolution are presented for both reduced and oxidized forms of perdeuterated Pyrococcus furiosus rubredoxin, a small iron–sulfur redox protein with remarkable thermostability. Hydronium ions may play a key role in the protonation and charge‐transfer processes associated with the oxidized and reduced forms of the protein.
