A, p-nitrophenol hydroxylase activity in human liver microsomes. p-Nitrophenol (100 μM) was incubated with liver microsomes (0.5 mg/ml protein) in the presence of an NADPH-regenerating system for 30 min at 37°C. Error bars represent S.E. B, correlation of p-nitrophenol hydroxylase and furan oxidase in human liver microsomes. A table displaying the numbers ± S.E. is available in the supplemental data.
