Recombinant Human CYP2D6

Cat. No.: CYP2D6-250H
Product Overview: Recombinant Human CYP2D6 was expressed in Baculovirus-Insect cells.
Description: This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and is known to metabolize as many as 20% of commonly prescribed drugs. Its substrates include debrisoquine, an adrenergic-blocking drug; sparteine and propafenone, both anti-arrythmic drugs; and amitryptiline, an anti-depressant. The gene is highly polymorphic in the population; certain alleles result in the poor metabolizer phenotype, characterized by a decreased ability to metabolize the enzyme"s substrates. The gene is located near two cytochrome P450 pseudogenes on chromosome 22q13.1. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
Source: Microsomes prepared from insect cells infected with a baculovirus containing a cDNA for human CYP2D6 (valine at position 374) and rabbit cytochrome P450 oxidoreductase (CYPOR)
Volume: 500 µL
Proteinconcentration: 8.5 mg/mL as determined using the BCA assay. Buffer: 100 mM potassium phosphate (pH 7.4), 20% glycerol, 1 mM DTT, 0.1 mM EDTA
Concentration of cytochromeP450: 1.0 nmol/mL
SpecificContent of cytochrome P450: 118 pmol spectral P450 per milligram of protein
Cytochrome P450 ReductaseActivity: 0.31 µmol of cytochrome c reduced per minute per milligram of protein
Bufuralol hydroxylaseactivity: 2.5 nmol/min/mg of protein. Bufuralol hydroxylation reactions were performed for 5 minutes at 37°C in 0.1 M potassium phosphate in the presence of 0.2 mM (+) bufuralol and 2 mM NADPH. The reaction was stopped by the addition of 0.2 volumes of 94% acetonitrile and 6% acetic acid. The mixture was spun in an Eppendorf centrifuge for ten minutes at maximum revolutions and 100 µL was removed for HPLC analysis.
HPLC conditions: 20 µL of sample was injected on to a 4.5 mm x 70 mm 3 µm C18 HPLC column. Solvent A: 30% acetonitrile, 70% water, 1 mM perchloric acid, Solvent B: 100% methanol. Initial conditions were 30% B for 1 minute followed by a gradient to 100% B over 6 minutes, then equilibration with 30% B for another 2 minutes. The amount of hydroxybufuralol was calculated by comparison to a standard curve of authentic (+) hydroxybufuralol.
Notes: A 5% decrease in bufuralol hydroxylation was observed after the microsomes had undergone 5 freeze-thaw cycles.
Storage: −80°C; Avoid multiple freeze-thaws
