Glucose-6-phosphate dehydrogenase (1.1.1.49) activity was assessed in 1986-1988 in blood samples from 1,521 individuals from 375 families living an Antalya city and adjacent villages by Beutler's fluorescence spot test. The families were randomly selected by the State Statistical Institute. Complete deficiency occurred in 7.4% of males and 1.8% of females. Mean enzyme activity was 6.77 +/- 1.07 IU/g Hb in normals and ranged between 0 and 0.48 IU/g Hb in those considered deficient. Kinetic measurements made with partially purified enzyme showed that GdB+ and GdB- variants were present in normal and in deficient subjects, respectively.
