    The crystal structure of a cyclic form of a mutant of bovine pancreatic trypsin inhibitor has been solved at 1.0 A resolution. The protein was synthesized by native chemical ligation and its structure is almost indistinguishable from the previously described recombinant form of the same mutant; however, the new loop containing the former termini became much better ordered.
