| Abstract: | Biosynthesis of chemicals has the advantages of high efficiency, green and sustainable development. Acetyl coenzyme A, as an important intermediate of cellular metabolism in cells, is an important precursor for the synthesis of many biochemicals, and has played a vital role in the process of microbial carbon metabolism. Here we reviewed the synthesis and strategies of metabolic regulation of acetyl coenzyme A in Escherichia coli and its important applications. We also summarized the synthesis pathway of acetyl coenzyme A and the recent development of metabolic regulation strategies to increase the intracellular metabolic flux of acetyl coenzyme A production, these including metabolic regulation of the acetyl coenzyme A synthesized by acetic acid and pyruvate, metabolic regulation of the central carbon metabolic pathway and acetyl coenzyme A synthesized by beta oxidation pathway, and discovery of new pathways for acetyl coenzyme A synthesis. Finally, we prospected the feasible strategies of increasing acetyl coenzyme A supply and discussed methods of constructing cell factories for synthesizing acetyl coenzyme A as precursor chemicals by genome editing technology. |
