ATP + H2O the enzyme protects citrate synthase and alcohol dehydrogenase from thermal aggregation and inactivation at 43°C and 50°C, respectively, and malate dehydrogenase from thermal inactivation at 80°C and 85°C. In the presence of ATP, the protective effects of alpha- and beta-subunits on citrate synthase from thermal aggregation and inactivation, and alcohol dehydrogenase from thermal aggregation, are more enhanced, whereas cooperation between chaperonins and ATP in protection activity on alcohol dehydrogenase and malate dehydrogenase (at 85°C) from thermal inactivation is not observed. Specifically, the presence of both alpha- and beta- subunits can effectively protect malate dehydrogenase from thermal inactivation at 80°C in an ATP-dependent manner Aeropyrum pernix ADP + phosphate
