[New variant of glucose-6-phosphate dehydrogenase (G-6-PD "Kaluga") from erythrocytes of a patient with chronic nonspherocytic hemolytic anemia].
Properties of a new form of glucose-6-phosphate dehydrogenase (G6PD) from erythrocytes, called "Kaluga", are described. The enzyme was isolated from erythrocytes of a patient with chronic non-spherocytic hemolytic anemia; in the blood cells 20% of the G6PD activity was maintained as compared with normal state. The partially purified enzyme was shown to be unstable in electrophoresis, it possessed a biphase type of pH-optima; Km value for NADP was decreased for glucose-6-phosphate Km value was normal. The thermostability of G6PD was normal at 46 within 1 hr.
