RESUMO
The activity of fructose-1,6-bisphosphate aldolase (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase, EC 4.1.2.13) in livers of fasted rabbits decreases to less than one-half the value found in livers of fed rabbits. However, the concentration of aldolase protein in the liver extracts, measured with a specific antibody, remains unchanged. More than twice as much antibody is required to neutralize the aldolase activity in liver extracts from fasted compared with fed rabbits. The results suggest that modification of liver aldolase occurs during fasting, resulting in loss of catalytic activity without loss of immunoreactivity.
