Hexose-6-phosphate dehydrogenase (H6PD) activity in washed hepatic microsomes from male ICR mice, when assayed with NADP+ and deoxyglucose-6-phosphate, was partially latent. Brief sonication or detergents activated H6PD causing an approximately 4- and 8.5-fold increase in NADPH generation respectively. The sonicated microsomes exhibited H6PD-linked N-demethylase activity toward aminopyrine. This activity was best sustained in the presence of deoxyglucose-6-phosphate, while galactose-6-phosphate, glucose-6-phosphate, and glucose were less effective. Reaction media containing sonicated microsomes, NADP+ and deoxyglucose-6-phosphate also catalyzed N-demethylation of p-chloro-N-methylaniline, N,N-dimethylaniline and nicotine, O-demethylation of p-nitroanisole, p-hydroxylation of aniline, ring hydroxylation of biphenyl at the 2- and 4-positions, dearylation of parathion, and the N-oxidation of N,N-dimethylaniline. In general, the hexose-6-phosphate dehydrogenase-linked monooxygenation rates were 60% or more of those observed in the presence of exogenous NADPH.
