    Abstract:
    Modification of microsomal membranes in vivo and in vitro results in changes of the glucose-6-phosphate and inorganic pyrophosphate phosphohydrolase activities of liver microsomal glucose-6-phosphate phosphohydrolase (EC 3.1.3.9). It was demonstrated that the glucose-6-phosphate phosphohydrolase activity of glucose-6-phosphatase depends on the content of phosphatidylethanolamine in the microsomal membranes, whereas the inorganic pyrophosphate phosphohydrolase activity seems to be dependent on the phosphatidylserine content. It is assumed that the regulation of the corresponding enzyme activities by these phospholipids is performed by the same allosteric mechanism in vitro and in vivo.
