title: [Solubilization and several properties of NAD-glucohydrolase isolated from rabbit heart].
abstract: Methods of isolation of NAD-glucohydrolase from the fraction of heart microsomes were searched for. NAD-glucohydrolase proved to pass into a soluble state under the effect of phospholipase A, triton X-100 and Na cholate. NAD-glucohydrolase was found to possess peculiar properties; it reversibly became denatured under the effect of 6M urea, but failed to become inactivated with own substrate (NAD) at pH 8.0. In case of  NAD-ases isolated from other sources the reversible denaturation by means of urea as a rule correlated with the enzyme inactivation in the presence of NAD at pH 8.0.
