Advances in Research on Heterologous Expression System of Secondary Metabolite Synthesis Gene Clusters of Actinomycetes

Heterologous expression of gene clusters has been widely used in the discovery of secondary metabolites of actinomycetes, the yield optimization, the analysis of biosynthetic pathways, and the construction of non-natural metabolite synthesis pathways.It has become one of the main strategies. In recent years, with the rapid development of high-throughput sequencing technology and gene editing technology, a large number of novel secondary metabolite synthesis gene clusters have been discovered.The heterologous expression plays an increasingly important role in studying secondary metabolites of actinomycetes. Based on this, the key role of heterologous expression technology in the study of secondary metabolites was reviewed, and its potential application prospects were prospected. The aim was to provide reference for the wider application of gene cluster heterologous expression technology.
