Glucose-6-phosphate dehydrogenase 葡萄糖-6-磷酸脱氢酶 , 硫酸铵悬浮液

cas:9001-40-5

Source: Leuconostoc mesenteroides

I.U.B.: 1.1.1.49

The Leuconostoc GPDH exhibits dual coenzyme specificity, namely NAD and NADP (Olive and Levy, Biochem., 6, 730 730, 1967). When assayed under conditions that are optimal for the particular coenzyme, the ratio of observed catalytic activity is NAD/NADP = 1.8.

Stability/Storage: The Leuconostoc mesenteroides glucose-6-phosphate dehydrogenase is a relatively stable enzyme in solution. The lyophilized and ammonium sulfate preparations are stable for 12 months when stored at 2-8°C.

Unit Definition: One Unit reduces one micromole of NAD per minute at 37°C, pH 7.8, using glucose-6-phosphate as substrate.
