Summary

The enzyme activity of phosphoglucomutase (PGM) has been investigated in red cell haemolysates from 142 individuals and compared to the sub-type as determined by isoelectric focusing. The 10 phenotypes showed significant differences in PGM-activity which indicates that there is a correlation between the level of activity and the isolelectric point of homozygotes. No indication of silent alleles or alleles with reduced activity was found in this collective.

Zusammenfassung

Die Enzymaktivität der erythrozytären Phosphogluco-mutase wurde in 142 Hämolysaten bestimmt. Die PGM-Phänotypen wurden mittels Isoelektrofokussierung auf Polyacrylamid-Gel ermittelt. Dabei konn-ten 10 verschiedene Phänotypen dargestellt werden. Die mittlere Enzymakti-vität dieser 10 Phänotypen weist signifikante Unterschiede auf. Ein stummes Allel bzw. ein Allel mit reduzierter PGM-Aktivität wurde nicht festgestellt. Es zeigte sich eine Korrelataion zwischen Enzymaktivität und isoelektrischem Punkt der vier Homozygoten.
