Pyruvate:flavodoxin oxidoreductase, the nifJ gene product of Klebsiella pneumoniae, was purified to homogeneity. Pyruvate:flavodoxin oxidoreductase, flavodoxin, and nitrogenase components I and II are the only proteins required for pyruvate-coupled nitrogenase activity. The physiological source of electrons to nitrogenase in K. pneumoniae is pyruvate. Flavodoxin from Azotobacter vinelandii was only one-third as effective as K. pneumoniae flavodoxin in transferring electrons from pyruvate:flavodoxin oxidoreductase to Azotobacter and Klebsiella nitrogenases. Ferredoxins from aerobic, anaerobic and photosynthetic nitrogen-fixing organisms, as well as benzyl viologen and methyl viologen, were ineffective in coupling pyruvate oxidation to nitrogenase activity. One mol each of acetyl-CoA, CO2, and ethylene are formed by pyruvate-supported acetylene reduction. The enzyme contains 8.0 +/-0.6 mol of iron and 6.6 +/-0.2 mol of acid-labile sulfide per mol of protein (Mr = 240,000). Pyruvate:flavodoxin oxidoreductase is irreversibly inactivated by air. << Less
