Abstract: | Conditions of phospholipase D adsorption on silica gels have been studied. The immobilized phospholipase D is shown to differ from the soluble form in thermostability, pH optima and activation conditions. A question is discussed as to the connection of the use of activators and the adsorption immobilization. It is assumed that phospholipase D belongs to enzymes, functioning only in the immobilized state. |
