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

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

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

Mechanistic studies with N-benzyl-1-aminobenzotriazole (BBT)-inactivated cytochrome P450 2B1 were conducted to determine which step(s) in the reaction cycle had been compromised. Stopped-flow studies, formation of the oxy-ferro intermediate, and analysis of products suggested that the reductive process was slower with
