Application

EC Number Application Comment Organism
1.14.14.1 biotechnology scanning chimeragenesis can be a useful method for producing new enzymatic products from CYP102A1 and may be used as a new systematic tool for changing substrate selectivity and regiospecificity among any two cytochromes P450 that have a common substrate, to study the interaction between enzymes and the substrate or to create new chimeric proteins for pharmaceutical and industrial uses Priestia megaterium

1.14.14.1 farnesol + [reduced NADPH-hemoprotein reductase] + O2 CYP102A1 oxidizes farnesol to three products (2,3-epoxyfarnesol, 10,11-epoxyfarnesol, and 9-hydroxyfarnesol), whereas CYP4C7 produces 12-hydroxyfarnesol as the major product. Chimeric proteins C(78-82,F87L) and C(78-82,F87L,328-330) show the most complete change in substrate selectivity from fatty acids to farnesol, and both retain superior enzyme activity with respect to CYP102A1 approximately 5times and approximately 2times greater, respectively. C(78-82,F87L,328-330) produces 12-hydroxyfarnesol as the major metabolite, as does CYP4C7 Priestia megaterium ?
