[Degradative pathways of glucose 1,6-diphosphate in human erythrocytes].
In this study human erythrocytes have been incubated with various effectors most of which able to decrease the G1, 6P2 content. By using haemolysates and partially purified phosphoglucomutase isoenzymes we provide evidence that the G1, 6P2 decrease can be attributed to the ability of phosphoglucomutase PGM2 isoenzymes to mutate various sugar monophosphates. These isoenzymes, phosphorylated by G1, 6P2, may transfer the phosphate group to monophosphate sugars thus releasing the respective bisphosphate.
