[ATP regulation strategy and its application in the synthesis of microbial metabolites]

Cofactor engineering, as a new branch of metabolic engineering, mainly involves ATP/ADP, NADH/NAD⁺, NADPH/NADP⁺ and other cofactors. Cofactor engineering can maximize metabolic flow by directly regulating the concentration and form of the cofactor of key enzymes in cells, and quickly direct carbon flow to target metabolites. ATP, as an important cofactor, is involved in many enzyme-catalyzed reactions in microbial cells, and leads to the restriction of the distribution of metabolic pathways by connecting or linking them into a complex network. Therefore, ATP regulation strategy is expected to be a favorable tool for industrial strain modification, to improve the concentration and production capacity of target metabolites, strengthen microbial tolerance to the environment and promote substrate utilization rate. The present review focuses on the recently used effective ATP regulation strategies and the effects of ATP regulation on cell metabolism in order to provide references for the efficient construction of microbial cell factories.
