Recently, Minh Nguyen’s paper about a novel method for protease specificity profiling using proteome-derived peptide libraries and tip-based substrate enrichment was accepted in the Journal of Proteome Research. The paper of Roeland Vanhoutte and Jan Pascal Kahler, both shared first authors, on novel clickable polyamine derivatives as probes for the polyamine transport system was featured on the inside back cover of ChemBioChem. Congrats to all authors!
