This is domain is found in Ferredoxin I (FdI), an Iron-sulfur ([Fe-S]) cluster-containing protein, present in species such as Azotobacter vinelandii. [Fe-S] proteins participate in electron transfer, catalytic, regulatory, and structural function. The FdI cluster exhibits a pH-dependent reduction potential and reversible protonation in the reduced state [1].	Domain
