glucose 6-phosphate dehydrogenase (g6pd) from streptomyces aureofaciens was purified and denatured in 6 m urea. denaturation led to complete dissociation of the enzyme into its inactive monomers, 98% loss of the enzyme activity, about 30% decrease in the protein fluorescence and a 10 nm red shift in the emission maximum. dilution of urea-denatured enzyme resulted in regaining of the enzyme acti...
