The assembly of six genes that encode enzymes from glutamate-fermenting bacteria converted Escherichia coli into a glutaconate producer when grown anaerobically on a complex medium. The new anaerobic pathway starts with 2-oxoglutarate from general metabolism and proceeds via (R)-2-hydroxyglutarate, (R)-2-hydroxyglutaryl-coenzyme A (CoA), and (E)-glutaconyl-CoA to yield 2.7 ± 0.2 mM (E)-glutaconate in the medium.
当在复杂培养基中进行厌氧生长时,来自谷氨酸发酵细菌的 6 种酶的基因的组装将大肠杆菌转化为戊二酸生产菌。新的厌氧途径从一般代谢中的 2-酮戊二酸开始,然后经过(R)-2-羟基戊二酸、(R)-2-羟基戊二酰辅酶 A(CoA)和(E)-戊二酰辅酶 A,在培养基中产生 2.7±0.2mM 的(E)-戊二酸。
