The biosynthesis of the organometallic H cluster of [Fe–Fe] hydrogenase requires three accessory proteins, two of which (HydE and HydG) belong to the radical S-adenosylmethionine enzyme superfamily. The third, HydF, is an Fe–S protein with GTPase activity. The [4Fe–4S] cluster of HydF is bound to the polypeptide chain through only the three, conserved, cysteine residues present in the binding sequence motif CysXHisX(46-53)HisCysXXCys. However, the involvement of the two highly conserved… CONTINUE READING
