Abstract

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 functional screening promises rapid characterization of catalytic potentials and utility of AoCYPs.

摘要

构建了来自米曲霉(Aspergillus oryzae)的细胞色素 P450 单加氧酶的功能性文库,其中 121 种同工型与酵母 NADPH-细胞色素 P450 氧化还原酶在酿酒酵母中共同表达。利用这个功能性文库,首次阐明了 AoCYPs 的新催化功能,如 CYP57B3 对染料木黄酮的催化潜力。全面的功能筛选有望快速表征 AoCYPs 的催化潜力和用途。
