Soil megacluster yields multi-target antibiotics against biotin biosynthesis

Researchers identified a megacluster of biosynthetic genes in Streptomyces that encodes four antibiotics—stravidins, acidomycin, α-Me-KAPA, and dapamycins—plus the biotin‑targeting protein streptavidin, all aimed at blocking vitamin B7 (biotin) production at different steps, a multi‑pronged approach that could slow resistance and guide new antibiotic development.

"Uncovering Soil Bacteria's Novel Antimicrobial Weaponry"

Researchers have discovered umbrella-shaped toxic protein particles secreted by soil bacteria Streptomyces to inhibit the growth of competing species, particularly others of their own genus. These large complexes, unlike small-molecule antibiotics, are highly specific in targeting bacteria and have evaded discovery for over a century. The discovery, published in Nature, sheds light on the bacteria's combative strategies and potential clinical applications, including combating antibiotic-resistant bacteria such as those causing tuberculosis and diphtheria.
