Nitrogen Fixation and Hydrogen Metabolism in Cyanobacteria [PDF]

Microbiology and Molecular Biology Reviews, 2010
SUMMARYThis review summarizes recent aspects of (di)nitrogen fixation and (di)hydrogen metabolism, with emphasis on cyanobacteria. These organisms possess several types of the enzyme complexes catalyzing N2fixation and/or H2formation or oxidation, namely, two Mo nitrogenases, a V nitrogenase, and two hydrogenases. The two cyanobacterial Ni hydrogenases
