Glucose-6-phosphate reduces microsomal SERCA hydrolytic activity, as quantified by decreased release of inorganic phosphate in comparison to other hexose phosphates tested. Glucose-6-phosphate (10 mM) significantly reduced (p < 0.05) the release of inorganic phosphate from brain ER microsomes after 6 min incubation. Neither glucose-1-phosphate (10 mM) nor fructose-6-phosphate (10 mM) altered phosphate release (p > 0.05) in comparison to control. Data are means ± SEM for n = 7. abMeans with differing superscripts are significantly different, p < 0.05, while means that share superscripts are not significantly different.
