Fragment-based identification of determinants of conformational and spectroscopic change at the ricin active site.
Bmc Struct.Biol., 7:72-72, 2007

PubMed Abstract: Ricin is a potent toxin and known bioterrorism threat with no available antidote. The ricin A-chain (RTA) acts enzymatically to cleave a specific adenine base from ribosomal RNA, thereby blocking translation. To understand better the relationship between ligand binding and RTA active site conformational change, we used a fragment-based approach to find a minimal set of bonding interactions able to induce rearrangements in critical side-chain positions.
