چکیده

Recent studies on microbial cytochrome P450 enzymes have covered several new areas. Advances have been made in structure-function analysis and new non-enzymatic/electrochemical systems for the replacement of NAD(P)H in biocatalysis have been developed. Furthermore, the properties of some enzymes have been re-engineered by site-directed mutagenesis or by methods of directed evolution and new P450s have been functionally expressed and characterized. It is thought that a combination of these approaches will facilitate the use of isolated P450 monooxygenases in biocatalysis.

Construction and application of a functional library of cytochrome P450 monooxygenases from the filamentous fungus Aspergillus oryzae.

A functional library of cytochrome P450 monooxygenases from Aspergillus oryzae (AoCYPs) was constructed in which 121 isoforms were coexpressed with yeast NADPH-cytochrome P450 oxidoreductase in Saccharomyces cerevisiae. Using this functional library, novel catalytic functions of AoCYPs, such as catalytic potentials of CYP57B3 against genistein, were elucidated for the first time. Comprehensive ...

Cytochrome P450 Monooxygenases in the Cotton Bollworm, Helicoverpa armigera (Lepidoptera: Noctuidae): In Vivo Effects of Deltamethrin Exposure

The in vivo effects of deltamethrin on Helicoverpa armigera cytochrome 450s were investigated by the measurements of cytochrome P450 content and two enzymatic activities. Deltamethrin showed dose-, tissue-, and exposure way-specific effects on cytochrome P450 monooxygenases, ranging from induction to repression. Topical deltamethrin (0.1 and 1.0 g insect) significantly decreased cytochrome P450...

Improved product-per-glucose yields in P450-dependent propane biotransformations using engineered Escherichia coli.

P450-dependent biotransformations in Escherichia coli are attractive for the selective oxidation of organic molecules using mild and sustainable procedures. The overall efficiency of these processes, however, relies on how effectively the NAD(P)H cofactors derived from oxidation of the carbon source are utilized inside the cell to support the heterologous P450-catalyzed reaction. In this work, ...
