Identification of 17- α-Ethynylestradiol Modified Active Site Peptides and Glutathione Conjugates Formed During Metabolism and Inactivation of P450s 2B1 and 2B6
The oral contraceptive 17-α-ethynylestradiol (17EE) is a mechanism-based inactivator of P450s 2B1 and 2B6. Inactivation of P450s 2B1 and 2B6 in the reconstituted system by [(3)H]17EE resulted in labeling of the P450 apo-protein. Mass spectral analysis of 17EE-inactivated P450 2B1 showed an increase...
