PG - 487-92 LID - 10.1016/j.ijbiomac.2010.03.008 [doi] AB - The effect of 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) on thermal aggregation of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from rabbit skeletal muscle at 45 degrees C has been studied using dynamic light scattering. In the presence of HP-beta-CD higher values of the rate of aggregation and larger aggregates were registered. The acceleration of GAPDH aggregation was due to destabilization of the enzyme molecule under the action of HP-beta-CD. This is evidenced by the data on thermal inactivation of GAPDH and differential scanning calorimetry. CI - Copyright 2010 Elsevier B.V. All rights reserved.
