theophylline + NADPH + O2 + H(+) = 3-methylxanthine + formaldehyde + NADP(+) + H2O
theophylline + nadph + o2 + h(+) = 3-methylxanthine + formaldehyde + nadp(+) + h2o
theophylline + NADPH + O2 + H(+) = 3-methylxanthine + formaldehyde + NADP(+) + H2O
theophylline + nadph + o2 + h(+) = 3-methylxanthine + formaldehyde + nadp(+) + h2o
