Enoyl-ACP reductase (FabI) was identified as a non-OYE 'ene'-reductase for asymmetric reduction of the C=C double bond of alpha, beta-unsaturated ketones. Reduction of several 2-alkylidenecyclopentanones with A-FabI and E-FabI gave (R)-2-alkylcyclopentanones in 95-90% and 70-81% ee, respectively. The product ee was improved to 99-98% in high yield by subsequent one-pot biooxidation.
烯丙基ACP还原酶(FabI)被鉴定为非OYE'烯'还原酶,用于不对称还原α,β-不饱和酮的C = C双键。用A-FabI和E-FabI还原几种2-亚烷基环戊酮,分别得到95-90%和70-81%ee的(R)-2-烷基环戊酮。通过随后的一锅式生物氧化,产物ee以高产率提高至99-98%。
