The Epstein-Barr virus determinant peptide EENLLDFVRF shows high immunogenicity when presented by HLA-B*4405 allotype. This fact is accompanied by a cis-trans isomerization of the Leu5-Asp6 peptide bond upon TCR binding of the pMHC complex. Molecular dynamics simulations of pMHC/TCR structures, with the EENLLDFVRF peptide in cis and trans conformations have been employed in order to examine the structure and dynamics of the pMHC complex with such an unusual conformation. The results, based on MM-PBSA free energy computations as well as buried surface area analysis and interactions at the pMHC/TCR interface, indicate that the TCR binds preferably the pMHC complex with the Leu5-Asp6 peptide bond in cis conformation. It is the first time that this notable conformational feature of T-cell epitope is investigated.
