Thermal stability of penicillin G acylase : effect of stabilizing agents.
The role of sugars, polyhydroxy compounds, phenylacetic acid and 6-aminopenicillanic acid in stabilization of immobilized penicillin G acylase (IMPGA) was studied. The loss in the activity of IMPGA at 50 degrees C, 2 h, after incorporation of sucrose and mannitol at 0.1 M concentration was 16 and 18% respectively; the loss in the activity of the enzyme under these conditions in the absence of stabilizing agents was 40%.
