 Title    The Expression of a Third Nitrogenase in the Cyanobacterium Anabaena variabilis  
 Abstract    Physiological experiments indicate that Anabaena variabilis can express either a V-or a Fe-nitrogenase in addition to the conventional, M o-containing enzyme complex. The occur­ rence o f the Fe-nitrogenase in A. variabilis can also be concluded from D N A -D N A hybridiza­ tion experiments using cloned anfW or nifW probes coding for the smaller subunit (= nitroge­ nase reductase) o f the Fe-nitrogenase from Azotobacter vinelandii or for the same subunit o f the M o-nitrogenase from Klebsiella pneumoniae. The cyanobacterium A. variabilis is the first phototroph found to contain all three nitrogenases landii as yet. Vanadium cannot substitute for M o in
