RSV Fusion Glycoprotein Engineered for the Prefusion State
PDB ID 4mmv includes the proof-of-principle study for the engineering of prefusion-stabilized RSV fusion glycoprotein. The protein includes several changes that stabilize the protein. A disulfide linkage was added between two amino acids that are very close to one another in the prefusion form but on opposite sides of the protein in the postfusion form. Several amino acids were modified to fill small pockets, further stabilizing the prefusion form. Finally, a short segment was added to the end of the chain to create a “foldon” that tightly associates the three chains.
