Preparation and properties of RNase T1 immobilized on aminoethyl Bio-Gel P-2.
The partially purified RNase T1, when coupled to glutaraldehyde activated aminoethyl Bio-Gel P-2, retained 22-24% activity of the soluble enzyme. Immobilization resulted in an increase in the optimum temperature and temperature stability, but it did not affect the pH optimum. Km and Vmax decreased as a result of immobilization. The bound enzyme showed high stability to repeated use and storage.
