Nature uses compact but functionalized biosynthetic fragments as building blocks to generate complex natural products. To leverage this strategy for the discovery of products with new scaffolds, we performed genome mining identify gene clusters (BGCs) in fungi that embed genes can synthesize targeted fragments. The three-enzyme pathway biosynthesizes strained dityrosine cyclophane herquline A was used a large number potential BGCs may use fragment. Characterization conserved BGC from fungal strains led isolation octacyclin A, an octacyclic product unprecedented structure, including two hetero-[3.3.1]bicycles and combination fused, bridged, macrocyclic rings. Biosynthetic steps leading were fully elucidated using reconstitution enzymatic assays, unveiling intriguing chemical logic reactions core. Our work demonstrates utility fragment-guided expanding space.

Natural products from fungi represent an important source of biologically active metabolites notably for therapeutic agent development. Genome sequencing revealed that the number biosynthetic gene clusters (BGCs) in is much larger than expected. Unfortunately, most them are silent or barely expressed under laboratory culture conditions. Moreover, many nature uncultivable cannot be genetically manipulated, restricting extraction and identification bioactive these species. Rapid exploration tremendous cryptic fungal BGCs necessitates development heterologous expression platforms, which will facilitate efficient production natural cell factories. Host selection, BGC assembly methods, promoters used expression, metabolic engineering strategies compartmentalization pathways key aspects consideration to develop such a microbial platform. In present review, we summarize current progress on above challenges promote research effort relevant fields.

Sea sponges are the largest marine source of small-molecule natural products described to date. Sponge-derived molecules, such as chemotherapeutic eribulin, calcium-channel blocker manoalide, and antimalarial compound kalihinol A, renowned for their impressive medicinal, chemical, biological properties. Sponges contain microbiomes that control production many isolated from these invertebrates. In fact, all genomic studies date investigating metabolic origins sponge-derived small molecules concluded microbes—not sponge animal host—are biosynthetic producers. However, early cell-sorting suggested host may play a role particularly in terpenoid molecules. To investigate genetic underpinnings biosynthesis, we sequenced metagenome transcriptome an isonitrile sesquiterpenoid-containing order Bubarida. Using bioinformatic searches biochemical validation, identified group type I terpene synthases (TSs) this multiple other species, first enzyme class characterized holobiome. The Bubarida TS-associated contigs consist intron-containing genes homologous feature GC percentage coverage consistent with eukaryotic sequences. We TS homologs five different species geographically distant locations, thereby suggesting broad distribution amongst sponges. This work sheds light on secondary metabolite speaks possibility sponge-specific originate host.

Pyridoxal 5′-phosphate (PLP)-dependent enzymes are the most versatile biocatalysts for synthesizing nonproteinogenic amino acids. α,α-Disubstituted quaternary acids, such as 1-aminocyclopentane-1-carboxylic acid (cycloleucine), useful building blocks pharmaceuticals. In this study, starting with biosynthesis of fusarilin A, we discovered a family PLP-dependent that can facilitate tandem carbon–carbon forming steps to catalyze an overall [3 + 2]-annulation. first step, cycloleucine synthases use SAM latent electrophile and in situ-generated enamine nucleophile γ-substitution. Whereas previously characterized γ-replacement protonate resulting α-carbon release acyclic acid, additional, intramolecular aldol or Mannich reaction nucleophilic form substituted cyclopentane. Overall, net 2]-annulation lead 2-hydroxy 2-aminocycloleucine products. These studies further expand biocatalytic scope enzymes.

Fusaric acid (FA) is a well-known mycotoxin that plays an important role in plant pathology. The biosynthetic gene cluster for FA has been identified, but the pathway remains unclarified. Here, we elucidated biosynthesis of FA, which features two-enzyme catalytic cascade, pyridoxal 5′-phosphate (PLP)-dependent enzyme (Fub7), and flavin mononucleotide (FMN)-dependent oxidase (Fub9) synthesizing picolinic scaffold. also involves off-line collaboration between highly reducing polyketide synthase (HRPKS, Fub1) nonribosomal peptide synthetase (NRPS)-like carboxylic reductase (Fub8) making aliphatic α,β-unsaturated aldehyde.
