alcohols into pyrophosphates that could be coupled to downstream isoprenoid biosynthesis. To be successful, each kinase in this pathway should be permissive of a broad range of substrates. For the first time, we have probed the promiscuity of the second enzyme in the ADH pathway-isopentenyl phosphate kinase from Thermoplasma acidophilum-towards a broad range of acceptor monophosphates. Subsequently, we evaluate
类异戊二烯是一类广泛的天然产物,用途广泛。由于在本质上仅提供了两个用于类异戊二烯生物合成的半萜烯构建基,所以用于制造类异戊二烯及其新的自然衍生物的合成生物学方法受到限制。为了解决这一局限性,人工化学酶促途径(例如依赖酒精的半萜(ADH)途径)可利用连续的激酶将外源性醇转化为焦磷酸,然后再将其与下游的类异戊二烯生物合成相结合。为获得成功,该途径中的每种激酶应允许广泛的底物。首次,我们检测了ADH途径中的第二种酶-嗜酸嗜热菌的异戊烯基磷酸激酶向广泛范围的受体单磷酸的混杂。
