9.B.393.1.1









DUF2231 protein of 178 aas and 4 TMSs. It is a rubredoxin_like; nonheme iron binding domain containing a [Fe(SCys)4] center. The family includes rubredoxins, a small electron transfer protein, and a slightly smaller modular rubredoxin domain present in rubrerythrin and nigerythrin.
