Integrated genomics and metabolomics survey of steroids from myxobacteria.

Dispersed sterol biosynthetic genes in myxobacteria enable discovery of 12 novel steroids, expanding the chemical diversity and potential pharmacological applications.

• Why it matters: Understanding steroid biosynthesis in myxobacteria is limited, hindering exploration of their ecological roles and therapeutic potential, and requiring new discovery strategies.
• What they did: A combined genomic and metabolomic approach analyzed myxobacterial genomes, revealing gene distribution patterns and using chromatographic pre-fractionation with NMR to isolate and characterize new steroids.
• The result: The study identified four previously unknown steroid structures, demonstrated synergistic antimicrobial activity, and established an integrated pipeline for uncovering cryptic metabolites and their biological functions.
