Enhancing Robustness of Sortase A by Loop Engineering and Backbone Cyclization.

Invited for the cover of this issue is Ulrich Schwaneberg and co-workers at RWTH Aachen University and DWI Leibniz-Institut für Interaktive Materialien. The image depicts a loop engineered, and backbone cyclized Staphylococcus aureus sortase A which shows enhanced robustness in site-specific protein and peptide modifications.
