Plant Cyclic Peptide Biosynthesis Paper Published!

Our paper on the biosynthesis of cyclopeptide alkaloids and related plant side chain cross-linked cyclopeptides is out now in Angewandte Chemie International Edition. We used bioinformatics and metabolomics to uncover a plant biosynthetic cassette responsible for these diverse cyclic peptides. We then applied these insights to find new natural products in Coffea arabica. Finally, we reconstituted the first enzyme activity for a split BURP peptide cyclase!
