生化/生理作用

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.
Cytochrome P450 enzymes are heme containing monooxygenases which are found primarily in the mammalian liver. They catalyze the oxidative metabolism of xenobiotics. This metabolism is the initial step in the biotransformation and elimination of a wide variety of drugs and environmental pollutants from the body. Quinidine is an inhibitor, whereas there is no known effective inducer of the enzyme. The isozyme CYP2D6 is a major pathway for the invivo conversion of dextromethorphan to dextrorphan via O-demethylation.

特点和优势

CypExpress^™ 2D6 is a permeabilized and stabilized dried yeast powder preparation containing full length, unmodified, human CYP 2D6 and recombinant human NADPH oxidoreductase. Using proprietary processes, CypExpress^™ are expressed in Pichia yeast. Following optimal expression, the cells are inactivated, permeabilized and dried to a fine powder. CypExpress^™ retains the cellular mechanisms to provide the P450 enzymes with the energy and cofactors to continue to function for long experiments, and can generate larger amounts of metabolite than mammalian microsomes or other genetically engineered expression systems. It is designed for rapid screening of drug metabolites and for scaling up metabolite generation.

单位定义

A reaction mixture containing 1 mM dextromethorphan and 100 mg/mL of CypExpress^™ 2D6 will produce 268.8 μM dextrorphan in 4 hours at 30℃ under the conditions described.
