Natural products are the result of Nature's exploration biologically relevant chemical space through evolution and an invaluable source bioactive small molecules for biology medicinal chemistry. Novel concepts discovery new compound classes based on natural product structure may enable wider space. The pseudo-natural concept merges relevance with efficient by means fragment-based development to inspire matter de novo combination fragments in unprecedented arrangements. novel scaffolds retain biological but not obtainable known biosynthetic pathways which can lead chemotypes that have unexpected or bioactivities. Herein, we cover workflow design development, highlight recent examples, discuss a cheminformatic analysis significant portion active synthetic compounds were found be products. We compare as human-made equivalent, i.e. structure.

Developing fungal heterologous expression platforms to explore and improve the production of natural products from fungal biodiversity

Biotechnology Advances, Год журнала: 2021, Номер 54, С. 107866 - 107866

Опубликована: Ноя. 12, 2021

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.

Terpene biosynthesis in marine sponge animals

Proceedings of the National Academy of Sciences, Год журнала: 2023, Номер 120(9)

Опубликована: Фев. 21, 2023

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.

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(21), С. 14672 - 14684

Опубликована: Май 14, 2024

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.
