A conserved E3 ubiquitin ligase rewires carotenoid, sterol, and lipid metabolism in Xanthophyllomyces dendrorhous

Eukaryotic cells must balance the biosynthesis of sterols, lipids, and in many organisms, carotenoids, which draw on shared acetyl-CoA-derived precursors. Our study identifies the ubiquitin ligase ...

Identification and distribution of a downregulatory signaling alkyloxazole in Streptomyces

Streptomyces use small molecules to dictate morphological development and secondary metabolism. Most of these signaling compounds are inducers derived from γ-butyrolactone (GBL)-synthesizing enzymes.

Dietary DNA in municipal wastewater reveals signatures of wealth, immigration, and coastal proximity

Poor diet is a leading driver of chronic disease worldwide, yet current dietary surveillance methods are costly, slow, and prone to bias. We introduce FoodSeq-FLOW (Food Landscape Observation in ...
