Phys.org / Drug discovery bottleneck? Cell-free platform screens peptides faster, even in harsh conditions

Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole (receptor) formed by a protein's three-dimensional structure and a molecule (ligand) that fits perfectly ...
