PhyloNaP: a user-friendly database of phylogeny for natural product-producing enzymes.

SUMMARY: Phylogenetic analysis is widely used to predict enzyme function, yet building annotated and reusable trees is labor-intensive and requires extensive knowledge about the specific enzymes. Existing resources rarely cover biosynthetic enzymes and lack the context needed for meaningful analysis. We present PhyloNaP, the first large-scale resource dedicated to phylogenies of biosynthetic enzymes. PhyloNaP provides ∼51 000 annotated and interactive trees enriched with chemical, functional, and taxonomic information. Users can classify their own sequences via phylogenetic placement, enabling functional inference in an evolutionary context. A contribution portal allows the community to submit curated trees. By combining scale, breadth of annotation, and interactive functionality, PhyloNaP fills a major gap in bioinformatics resources for enzyme discovery and annotation, with immediate applications to secondary metabolism and beyond. AVAILABILITY AND IMPLEMENTATION: Freely available on the web at https://phylonap.cs.uni-tuebingen.de.

Animating insights into the biosynthesis of glycopeptide antibiotics.

The realm of natural product (NP) research is constantly expanding, with diverse applications in both medicine and industry. In this interdisciplinary field, scientists collaborate to investigate various aspects of NPs, including understanding the mode of action of these compounds, unraveling their biosynthetic pathways, studying evolutionary aspects, and biochemically characterizing the enzymes involved. However, this collaboration can be challenging as all parties involved come from very different backgrounds (such as microbiology, synthetic chemistry, biochemistry, or bioinformatics) and may not use the same terminology. Fortunately, contemporary technologies, such as videos, provide novel avenues for effective engagement. Recognizing the potency of visual stimuli in explaining complex processes, we envision a future where animations become more and more common in interdisciplinary communication, accompanying perspectives, and reviews. To demonstrate how such approaches can enhance the understanding of complex processes, we have animated the biosynthesis of the glycopeptide antibiotic vancomycin (https://youtu.be/TGAgC4c8hvo).
