Improved Amplex Red Screening of CYP119 Variants
2026-08-22
Başlar and colleagues developed an Amplex Red peroxidation assay that enables rapid screening of hydrogen peroxide-dependent cytochrome P450 activity in cell lysates. Applying the method to a CYP119 active-site library identified the T213R/T214I variant, which combined higher catalytic turnover with improved resistance to peroxide-associated heme degradation, while also revealing substrate-specific tradeoffs.
