Sequence of a human liver cytochrome P-450 cDNA clone.
The following nucleotide sequence (P450 HPH) has been cloned from cDNA library of adult human liver in Xgtll by immunoscreening method. We used polyclonal antibodies against cytochrome P-450 from phenobarbital-pretreated rats. The sequence is essentially identical to the sequences Hpl — 1 and M-12 described by (1) and (2) respectively for the P-450 IIC8 type gene. The sole difference in the tra...
متن کاملHydroxylation and demethylation of the tricyclic antidepressant nortriptyline by cDNA-expressed human cytochrome P-450 isozymes.
The metabolism of nortriptyline was studied in vitro using cDNA-expressed human cytochrome P450 isozymes 1A2, 3A4, 2C19, and 2D6, CYP2D6 was the sole isozyme mediating hydroxylation of nortriptyline, the quantitatively most important metabolic pathway, and only (E)-10-OH-nortriptyline was formed. CYP2D6, 2C19, and 1A2, mentioned in decreasing order of significance, mediated the demethylation re...
متن کاملQuantification of cytochrome P-450 gene expression in human tissues.
Humans can metabolize an extremely wide range of potentially harmful foreign hydrophobic compounds including many drugs, environmental pollutants and chemical carcinogens. This ability is mainly due to the action of cytochromes 1’-450. These proteins constitute a large superfamily that has been classified into several families, the largest of which (P45011) has been further divided into seven s...
متن کاملMetabolism of theophylline by cDNA-expressed human cytochromes P-450.
1. Theophylline metabolism was studied using seven human cytochrome P-450 isoforms (CYPs), namely CYP1A1, 1A2, 2A6, 2B6, 2D6, 2E1 and 3A4, and microsomal epoxide hydroxylase (EH), expressed in human B-lymphoblastoid cell lines. 2. At a high theophylline concentration of 10 mM four CYPs (1A1, 1A2, 2D6, 2E1) catalyzed the metabolism of theophylline. 3. Theophylline had the highest affinity (appar...
متن کاملNucleotide sequence of the unique nitrate/nitrite-inducible cytochrome P-450 cDNA from Fusarium oxysporum.
A cDNA clone for the nitrate/nitrite-inducible cytochrome P-450 (P-450) of the fungus Fusarium oxysporum (tentatively termed P-450dNIR) was isolated by an immunoscreening method. Sequence determination revealed a polypeptide of 403 amimo acid residues (Mr = 44,371), which was shown to contain the full-length sequence of the fungal P-450. The amino terminus region of the predicted sequence conta...
