Abstract:
:The early and late effects of alloxan-diabetes and insulin treatment on kinetic properties of mitochondrial FoF1 ATPase were examined. Diabetic state resulted in significant decrease in the activity while insulin treatment caused hyper-stimulation. In control animals the enzyme activity resolved in three kinetic components. In diabetic condition only component I and II were present. With insulin treatment component III was restored but component II was abolished. Diabetic state and insulin treatment had varied effects on Km values of the three components, whereas the Vmax values were generally on the higher side. Evaluation of the AppKcat/Km values revealed that diabetic state resulted in increased catalytic efficiency; insulin treatment brought back these values to normality. Temperature kinetics studies indicated that the phase transition temperature decreased significantly in the diabetic and insulin-treated diabetic animals. The energy of activation in low temperature range increased in the diabetic animals. Insulin treatment corrected the Arrhenius pattern at early stage of diabetes; at late stage the pattern was reversed. The results are suggestive of subtle insulin-status-dependent alterations in membrane structure - function relationships.
