This paper describes the utilisation of methoxy-resorufin ether as an electrochemical probe for studying cytochrome P450 CYP6G1. Methoxy-resorufin ether is well established as a versatile substrate for cytochrome P450, as its demethylated product, resorufin, is a fluorophore. We show that

Some eukaryotic cytochromes P450 (P450s) have a series of ionic amino acids, corresponding to Lys250, Arg251, and Lys253 residues in the P450 1A2 sequence. To understand the roles of those ionic amino acids in the catalytic function of P450, three

Dioxins have been shown to bind and induce rodent CYP1A2, producing a dose-dependent hepatic sequestration in vivo. The induction of CYP1A2 activity has been used as a noninvasive biomarker for human exposure to dioxins; while there is a consistent relationship

As part of an ongoing effort to understand aryl hydrocarbon receptor (AhR) mediated toxicity in mink, cDNAs encoding for CYP1A1 and the CYP1A2 mixed function monooxygenases were cloned and characterized. In addition, the effects of selected dibenzofurans on the expression

1. Cytochrome P4501A2 (CYP1A2) activates a large number of procarcinogens to carcinogens. Phytochemicals such as flavones can inhibit CYP1A2 activity competitively, and hydroxylated derivatives of flavone (galangin) may be potent, selective inhibitors of CYP1A2 activity relative to CYP1A1 activity.
