Schematic representation of a putative confurcating formate dehydrogenase, two putative confurcating [FeFe]-hydrogenases and two ferredoxin re-oxidizing [FeFe]-hydrogenases in Desulfotomaculum kuznetsovii. Gene locus tag numbers and α-, β-, and γ-subunits are depicted. Moreover, predicted iron-sulfur clusters and metal-binding sites are indicated.
