What is Microbial Natural Products and Biosynthesis?
Microbial natural products and biosynthesis is the study of secondary metabolites produced by microorganisms through biosynthetic gene clusters, serving as key sources for drug discovery via genome sequencing and exploration of microbial metabolites including those from marine sources and endophytic fungi.
This field encompasses 424,501 papers focused on natural products from microbial sources as potential new drugs. It covers genome sequencing, biosynthetic gene clusters, secondary metabolites, antibiotics, nonribosomal peptides, and polyketide biosynthesis. The cluster highlights marine natural products and endophytic fungi for bioactive pharmaceutical compounds.
Topic Hierarchy
Research Sub-Topics
Biosynthetic Gene Cluster Discovery
This sub-topic employs genome mining and metagenomics to identify silent BGCs in microbial genomes. Researchers activate cryptic pathways using genetic engineering and comparative genomics.
Nonribosomal Peptide Biosynthesis
This sub-topic studies NRPS enzyme complexes that assemble peptide natural products like vancomycin. Researchers engineer modular synthetases for novel peptide structures and analyze substrate specificity.
Type I Polyketide Synthases
This sub-topic investigates modular PKS assembly lines producing macrolides like erythromycin. Researchers map domain functions and perform combinatorial biosynthesis for analog generation.
Marine Microbial Natural Products
This sub-topic explores secondary metabolites from marine actinomycetes and fungi with unique carbon skeletons. Researchers culture uncultivables and apply OSMAC strategies for dereplication.
Endophytic Fungal Secondary Metabolites
This sub-topic investigates bioactive compounds from plant-associated endophytic fungi. Researchers apply metabolomics and phylogenomics to discover anticancer and antimicrobial leads.
Why It Matters
Microbial natural products provide approved therapeutic agents, with Newman and Cragg (2020) documenting their role over nearly four decades from 1981 to 2019, including updates from prior reviews covering 39 years of data. For instance, their analysis in "Natural Products as Sources of New Drugs over the Nearly Four Decades from 01/1981 to 09/2019" (5960 citations) extends prior works like "Natural Products as Sources of New Drugs from 1981 to 2014" (5711 citations), showing consistent contributions to pharmacology. Marine natural products from microorganisms, phytoplankton, algae, and invertebrates are reviewed in "Marine natural products" (1990, 4885 citations), emphasizing isolation of 829 compounds in 2008 alone for drug leads.
