WebNatural products biosynthesized by cryptic gene clusters represent a largely untapped source for drug discovery. However, mining of these products by promoter engineering is restricted by the lack of streamlined genetic tools, especially in nonmodel biosynthetic gene cluster (BGC)-rich bacteria. WebThe major hindrance for obtaining such bioactive compounds from Streptomyces is that most of the compounds are not produced in significant titers, or the biosynthetic gene clusters (BGCs) are cryptic. The rapid development of genome sequencing has provided access to a tremendous number of NP-BGCs embedded in the microbial genomes.

Activating cryptic biosynthetic gene cluster through a …

WebJun 7, 2024 · We recently devised a chemogenetic high-throughput screening approach (“HiTES”) to discover small molecule elicitors of silent biosynthetic gene clusters. This method was successfully applied to a Gram-negative bacterium; it has yet to be implemented in the prolific antibiotic-producing streptomycetes. WebHere we report the identification, isolation and structure elucidation of coelimycin P1, an unusual yellow-pigmented metabolic product of the cpk cryptic polyketide biosynthetic gene cluster of Streptomyces coelicolor M145, using a genetic engineering strategy designed to increase metabolic flux through the biosynthetic pathway. cif ieb

Novel antibiotic screening methods to awaken silent or cryptic

WebJun 12, 2024 · These biosynthetic gene clusters (BGCs) are signatures for fungal genomes comprising co-localized contiguous genomes, and they participate in the same metabolic pathways. ... DNA methylation and histone modification causing agents modulate and induce cryptic fungal gene clusters. For example, 5-aza-20-deoxycytidine, 5 … WebOct 12, 2016 · Sponge metagenomes are a useful platform to mine cryptic biosynthetic gene clusters responsible for production of natural products involved in the sponge-microbe association. Since numerous sponge-derived bioactive metabolites are biosynthesized by the symbiotic bacteria, this strategy may concurrently reveal sponge-symbiont produced … WebMicrobial genome sequencing has uncovered a myriad of natural products (NPs) that have yet to be explored. Bacteria in the genus Pseudomonas serve as pathogens, plant growth promoters, and therapeutically, industrially, and environmentally important microorganisms. Though most species of Pseudomonas have a large number of NP biosynthetic gene … cif idesa industrial plants slu
