Today the first, first-author manuscript for UQ PhD student Colton Payne came out in bioRXiv. It's NMR-centric work on helical hairpin peptides. Colton is based in the Rosengren lab at UQ.

About the Mylne lab at UWA

Our research has two separate foci; applied work on herbicides and fundamental research on biosynthesis and the genetic events that evolve new plant proteins. Our herbicide research aims to find as many new modes of action possible, whereas our more protein evolution work gives insight into biosynthesis and enzymology.

Our applied herbicide work started with our finding that, thanks to the established close evolutionary relationship between plants and the malarial parasites, many antimalarial drugs are also herbicidal. After trawling antimalarial drug libraries for novel herbicide chemistries, we now are focused on discovering novel modes of herbicide action. Our fundamental protein evolution work is based on biosynthesis for different classes of peptides, mostly cyclic ones and many whose sequences are buried in precursors for unrelated proteins. Is this a more universal mechanism for creating new proteins that bypasses the need for a completely new gene?
