The microsomal O-deethylation of a novel coumarin analog, 7-ethoxy-4-trifluoromethylcoumarin (EFC), to a fluorescent product was characterized. Results indicate that this analog provides a rapid, convenient and highly sensitive means to assay cytochrome P-450-mediated metabolism. Like microsomal 7-ethoxycoumarin (7-EC) O-deethylation, EFC

Tetranychus urticae Koch has recently developed resistance to chlorfenapyr in Australia and Japan, but no attempt has yet been made to describe the biochemical mechanisms involved in chlorfenapyr resistance. In this study a laboratory-selected chlorfenapyr-resistant strain was investigated. Resistance to

Improvement of CYP2B6 expression was examined by co-expression with molecular chaperones GroES/EL. Although a CO-reduced difference spectrum was not detected in Escherichia coli transformed only by the CYP2B6-expressing vector, co-expression of GroES/EL resulted in high-level expression which reached over 2000

To investigate their potential roles in ligand access, binding, and subsequent metabolism, residues in the N-terminal portion of the cytochrome P450 2B1 I helix were mutated to alanine and phenylalanine. Of the 18 mutants from E286 to S294 only 7

Until recently, all known structures of bacterial cytochromes P450 suggested that substrate access to the buried active site occurred via the F-G region, a surface loop distal to the heme cavity. However, the structure of P450 51 indicates a large
