[Effect of oxygen on the transformation of ribulose-1,5-diphosphate in the hydrogen bacterium Hydrogenomonas eutropha].
Oxygenase transforamtion of ribulose-1,5-diphosphate was found in the hydrogen bacterium Hydrogenomonas eutropha Z-1. Oxygen inhibits the carboxylating activity of ribulose-1,5-diphosphate carboxylase by 42% at a low concentration of the substrate of carboxylation--bicarbonate. The oxygenase activity of this carboxylase is saturated at 50% of oxygen in the atmosphere.
