Research interests of the AG Teufel

The Teufel laboratory provides an excellent opportunity for students who wish to explore microbial secondary metabolic pathways and exceptional enzymatic reactions that give rise to pharmaceutically relevant natural products. Our studies currently mainly aim to unveil novel flavin-dependent enzyme reactions that play pivotal roles in the generation of structurally complex pharmacophores. The importance of the flavin cofactor for countless redox reactions was recognized long ago, albeit mechanistic studies were heavily focused on a moderate assortment of primary metabolic flavoenzymes. While this granted deep insight into many aspects of flavin-dependent catalysis, the more recent detailed biochemical characterization of secondary metabolic pathways has proven a true treasure trove for flavin enzymology and unearthed a broader catalytic diversity. It appears that the unmatched versatility of flavoenzymes is ideally suited for secondary metabolism, nature’s biosynthetic tinkering ground, and significantly contributes to the vast chemical and functional diversity of natural products such as antibiotics or anticancer agents.
