This disclosure describes enzymes from the type II (a discrete set of enzymes) fatty acid synthesis (“FAS”) pathway that can be used in combination with thiolases to operate a functional reversal of the β-oxidation cycle. A combination of thiolases with one or more of 3-oxoacyl-[acyl-carrier-protein] reductase (FabG, others), 3-hydroxyacyl-[acp] dehydratase (FabA, FabZ, others), and enoyl-[acyl-carrier-protein] reductase (FabI, FabK, FabL, FabV, others) yields a functional reversal of the β-oxidation cycle. If only one or two enzymes are used, the remaining enzymes will be traditional beta oxidation enzymes. Once this cycle is coupled with the appropriate priming and termination pathways, the production of carboxylic acids, alcohols, hydrocarbons, amines and their α-, β-, and ω-functionalized derivatives from renewable carbon sources can be achieved.
本公开内容描述了 II 型(一组独立的酶)脂肪酸合成("FAS")途径中的酶,这些酶可与硫醇酶结合使用,以实现 β 氧化循环的功能性逆转。将硫醇酶与 3-氧代酰基-[酰基载体-蛋白]还原酶(FabG,其他)、3-羟基酰基-[acp]脱水酶(FabA、FabZ,其他)和烯酰基-[酰基载体-蛋白]还原酶(FabI、FabK、FabL、FabV,其他)中的一种或多种结合使用,可产生β-氧化循环的功能性逆转。如果只使用一种或两种酶,剩余的酶将是传统的β氧化酶。一旦这个循环与适当的启动和终止途径相结合,就可以从可再生碳源生产出羧酸、醇、碳氢化合物、胺及其 α-、β- 和 ω-官能化衍生物。
