Model of the structure of formate dehydrogenase coupled hydrogenases. FHL of E. coli (A) has the physiological function of formate oxidation coupled to H2 formation. The FHL consist of a [NiFe] hydrogenase coupled to a formate dehydrogenase and membrane integral subunits. In contrast, the HDCR of A. woodii (B) is composed of a [FeFe] hydrogenase coupled to a formate dehydrogenase and catalyzes reversible CO2 reduction with H2 as electron donor.
