The hydrogen atoms of [4Fe-4S] type ferredoxin, one of the electron carriers, have been visualized and both experiments and calculations have revealed the mechanisms that control the redox potential. Aspartic acid (Asp64) located a distance away from the [4Fe-4S] cluster of ferredoxin, was found to be the control switch, an evolutionarily conserved mechanism.
Uncovered a mystery of ‘electron carrier’ existing in all living organisms: Discovery of a ‘nano-switch mechanism’ controlled by a single hydrogen atom
