Molecular Hydrogen
N2-fixing organisms also produce a membrane bound enzyme called uptake-hydrogenase under N2-fixing condition. The physiological significance of the presence of uptake hydrogenase lies in its ability to consume hydrogen produced during nitrogenase activity through aerobic electron transport chain generating ATP in the process. Such nitrogenase uptake-hydrogenase relationship in nitrogen fixing cells provides the following advantages:
It has been observed that the nitrogenase enzyme catalyses exclusive production of hydrogen provided the N2-fixer is in an atmosphere devoid of nitrogen. Efforts are being made to exploit this special property of the enzyme for photo production of H2 by heterocysts of cyanobacteria on a commercial scale. This would require construction of special strains of cyanobacteria that would be genetically deficient in uptake hydrogenase enzyme. It. is expected that these strains would continuously generate hydrogen in photosynthetic and N2-fixing condition.
