The control of glucose 1,6-bisphosphatase by Ca2+ and calmodulin
Abstract:
1. The control of glucose 1,6-bisphosphatase activity, the enzyme that degrades glucose 1,6-bisphosphate, a metabolite that regulates hexose phosphate metabolism, has been examined in a rat muscle extract. 2. The enzyme has been found to be activated by physiological Ca2+ concentrations. Ca2+ can be replaced by Sr2+ and Mn2+, but the effects are not so pronounced. 3. The Ca2+ effect is inhibited by EGTA. Trifluoperazine also inhibits enzyme activity. This effect can be reversed by adding exogenous calmodulin.
