Biochem/physiol Actions

Cytochrome P450 is a heterogeneous family of isozymes whose primary function is to oxidize small molecules, both as a function of intermediary metabolism (e.g., fatty acids) and to detoxify exogenous compounds (drugs or toxins). Some isoforms have narrow substrate specificity, while others are promiscuous.
The CYP1A1 isoform catalyzes 7-deethylation of ethoxyresorufin.

Physical form

Solution in 100 mM potassium phosphate buffer, pH 7.4.

Preparation Note

Microsomes containing human CYP1A1 and recombinant human NADPH-P450 reductase.
