Abstract
With the development of sequencing technology and further scientific research, an increasing number of biosynthetic gene clusters associated with secondary Streptomyces metabolites have been identified and characterized. The encoded genes of a family of regulators designated as PAS-LuxR are gradually being discovered in some biosynthetic gene clusters of polyene macrolide, aminoglycoside, and amino acid analogues. PAS-LuxR family regulators affect secondary Streptomyces metabolites by interacting with other family regulators to regulate the transcription of the target genes in the gene cluster. This paper provides a review of the structure, function, regulatory mechanism, and application of these regulators to provide more information on the regulation of secondary metabolite biosynthesis in Streptomyces, and promote the application of PAS-LuxR family regulators in industrial breeding and other directions.
