The Anti-Biotin Megacluster of Streptomyces
Microbiology Breakthrough Overcoming Resistance: The Anti-Biotin Megacluster of Streptomyces How a newly mapped genomic "super-weapon" enforces absolute starvation on drug-resistant pathogens A groundbreaking study published in the journal Nature by an international team of researchers at McMaster University has unveiled an unprecedented genetic phenomenon within soil-dwelling Streptomyces bacteria. Scientists have successfully mapped a massive, co-located biosynthetic genomic region dubbed a "megacluster." While classic bacterial genomes typically feature isolated Biosynthetic Gene Clusters (BGCs) dedicated to producing a single antibiotic compound, this newly discovered mega-locus completely breaks the conventional rules of microbial genomics. It contains four distinct, co-localized families of natural product antibiotics functioning within a single genetic region. This molecular battery includes one chemical c...
