Reaction of ethanol radicals with ribonuclease.
Ribonuclease was irradiated under conditions such that ethanol radicals were the main reactive species in solution. Sephadex gel filtration of the irradiated solution demonstrated that ethanol radicals had reacted with the ribonuclease and had become firmly bound to the enzyme molecule. The number of ethanol molecules bound to ribonuclease was a function of dose and correlated with the loss of enzymatic activity and with the changes in the molecular configuration of the enzyme molecule.
