Biochem/physiol Actions

The enzyme catalyses electron transfer to cytochrome P450. This system plays a major role in detoxification of drugs and xenobiotics, activation of carcinogens, and metabolism of endogenous substrates such as steroids.

Packaging

Package size based on protein content.

Unit Definition

One unit will catalyze the reduction of 1.0 μmole of cytochrome c by NADPH per min at pH 7.7 at 30 °C.

Physical form

Solution in 30 mM potassium phosphate buffer, pH 7.7, and 0.1 mM EDTA containing 50%(v/v) glycerol.
