In a designed fusion protein the trimeric domain foldon from bacteriophage T4 fibritin was connected to the C terminus of the collagen model peptide (GlyProPro)(10) by a short Gly-Ser linker to facilitate formation of the three-stranded collagen triple helix. Crystal structure analysis at 2.6 A resolution revealed conformational changes within the interface of both domains compared with the structure of the isolated molecules. A striking feature is an angle of 62.5 degrees between the symmetry… CONTINUE READING
