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

Tamoxifen is primarily used in the treatment of breast cancer. It has been approved as a chemopreventive agent for individuals at high risk for this disease. Tamoxifen is metabolized to a number of different products by cytochrome P450 enzymes. The

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

In this study, we have evaluated the use of ultra-sterile alginate hydrogels encapsulated with HepG2 liver cells for applications in high throughput drug screening. We have studied the cellular viability and metabolic capacity of the encapsulated cells in two different
James R Reed et al.

The metabolism of selected substrates by cytochromes P450 (P450) 2B1, 2B4, and 2B6 was compared, and the effects of cytochrome b(5) (b(5)) on these reactions were assessed. There did not appear to be any trends regarding the effects of b(5)
