Abstract
Some rhizobia induce a hydrogen (H2)-uptake system with a [NiFe] hydrogenase along with nitrogenase to recover part of the energy lost as H2. Biosynthesis of NiFe hydrogenases is a process that ocurrs in the cytoplasm, where a number of auxiliary proteins (products of hup and hyp genes) are required to synthesize and insert the metal cofactors into the enzyme structural units. Although HypC is expressed in all hydrogenase systems, HupF and HupK are found only in bacteria that express the hydrogenase in the presence of oxygen (O2). Co-purification experiments have demonstrated HypC-HupK and HypC-HupL interactions. Results have shown that some conserved residues from HypC and HupK play a protective role of hydrogenase against the presence of O2.
