Epitope structures were obtained by using the PEP-FOLD-3.5 web-server; the HLA allele's structures were retrieved from the RCSB-PDB database. In Table 4 the crystal structure/model structure details with reference PDB-Id is provided. Table 4 Listing of MHC HLA-Alleles respective Crystal structures/Models with the PDB ID.
