[Glucose 1,6-diphosphate in the erythrocytes of various species of mammal].
Red blood cells from human, pig, cow, rabbit, rat and sheep were investigated for the occurrence of phosphoglucomutase multiple forms, G1,6P2 level, PGM, PRM and G1,6P2 synthetic activities. In all cases a species specific pattern of PGM isoenzymes was detected by starch gel electrophoresis. G1,6P2 mean values range from 33 to 122 nmol/ml RBC for pig and rabbit erythrocytes, respectively. The study of the correlation between the biphosphate content and the occurrence of the three measured enzymatic activities indicates a possible role of PRM activity (property of PGM2 isoenzymes) in the erythrocytic G1,6P2 catabolism.
