An engineered microbe that contains a designed platform for the conversion of one-carbon substrates to chemical products is described. The designed platform embodies a new metabolic architecture that consolidates carbon fixation, central metabolism, and product synthesis into a single pathway. This is made possible by the key finding that 2-hydroxyacyl-CoA lyase, an enzyme in the α-oxidation pathway, is capable of catalyzing the C—C bond formation between formyl-CoA and aldehydes of different chain lengths, allowing for the elongation of the carbon backbone of said aldehyde by one-carbon units. These novel microbes present an opportunity for the production of chemicals from single-carbon feedstocks such as carbon dioxide, carbon monoxide, formate, formaldehyde, methanol or methane.
本文描述了一种工程微生物,它包含一个将一碳底物转化为化学产品的设计平台。所设计的平台体现了一种新的代谢结构,它将碳固定、中心代谢和产物合成整合为一条途径。之所以能够做到这一点,关键在于α-氧化途径中的一种酶--2-羟基乙酰-CoA 裂解酶能够催化甲酰-CoA 与不同链长的醛之间形成 C-C键,从而使所述醛的碳骨架延长一个碳单位。这些新型微生物为利用二氧化碳、一氧化碳、甲酸盐、甲醛、甲醇或甲烷等单碳原料生产化学品提供了机会。
