The erythrocyte G-6-PD activity was 10.4% of normal. The enzyme did not use 2-deoxyG-6-P, galactose-6-phosphate, and DPN as cofactor. DeaminoTPN utilization was 40.7% that of TPN. Michaelis constants for G-6-P and TPN were 70 and 2.1 μM respectively. This new G-6-PD variant is named G-6-PD Intanon after the name of the mountain on which the subject lived. © 1974 Springer-Verlag.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyMedicineArticleSCOPUS10.1007/BF00281039
