[Production and properties of an immobilized enzyme preparation with peptidase activity].
A heterogeneous multienzyme preparation with the peptidase activity, isolated from the cells of Pseudomonadacea bacteria, was immobilized on alumina. The specific activity of the immobilized enzyme complex is not a simple function of the bound protein quantity, but depends on immobilization conditions. An additional glutaraldehyde treatment results in higher thermostability of the immobilized enzyme preparation. The substrate specificity of the preparation retains after immobilization, and it becomes less sensitive to pH changes.
