isolated, cloned, heterologously expressed and characterized a thermostable old yellow enzyme (OYE) from Geobacillus kaustophilus. In addition to the expected ‘enone’ reduction, GkOYE also catalyzes the reverse reaction, i.e., the desaturation of CC bonds adjacent to a carbonyl to give the corresponding α,β-unsaturated ketone. The reaction proceeds at the expense of molecular oxygen without the need
极端微生物的酶由于对各种应激因素的耐受性而一直对生物技术非常感兴趣。我们已经分离,克隆,异源表达并表征了来自嗜碱芽孢杆菌的热稳定的旧黄色酶(OYE)。除预期的“烯酮”还原外,Gk OYE还催化逆反应,即与羰基相邻的CC键脱饱和,得到相应的α,β-不饱和酮。该反应以分子氧为代价而无需烟酰胺辅因子进行,并且代表了对已知化学脱氢方法的环境友好的替代方案。
