Computation-guided backbone grafting of a discontinuous motif onto a protein scaffold. Science, 334:373-376, 2011 Cited by PubMed Abstract: The manipulation of protein backbone structure to control interaction and function is a challenge for protein engineering. We integrated computational design with experimental selection for grafting the backbone and side chains of a two-segment HIV gp120 epitope, targeted by the cross-neutralizing antibody b12, onto an unrelated scaffold protein. The final scaffolds bound b12 with high specificity and with affinity similar to that of gp120, and crystallographic analysis of a scaffold bound to b12 revealed high structural mimicry of the gp120-b12 complex structure. The method can be generalized to design other functional proteins through backbone grafting. PubMed: 22021856DOI: 10.1126/science.1209368 PDB entries with the same primary citation |
