%X UNASSIGNED: The current in silico study was done to determine the primary biochemical features and immunogenic epitopes of Echinococcus granulosus glutathione S-transferase protein as a potential vaccine candidate.
UNASSIGNED: Several web tools were employed to predict physico-chemical properties, antigenicity, allergenicity, solubility, post-translational modification (PTM) sites, subcellular localization, signal peptide, transmembrane domain, secondary and tertiary structure followed by refinement and validations. In addition, B-cell epitopes were predicted and were screened using various web servers, while MHC-binding and CTL epitopes were predicted using IEDB and NetCTL servers, respectively.
UNASSIGNED: The protein had 219 residues with a molecular weight of 25.55 kDa and alkaline isoelectric pH (7.5). This protein was stable, thermo-tolerant (aliphatic index: 78.04) and hydrophilic (GRAVY: -0.440). The predicted antigenicity scores were low and the protein was nonallergenic in nature. There were no transmembrane domain and signal peptide in the sequence. Moreover, several B-cell, MHC-binding and CTL epitopes were found in the EgGST protein, which could be further used in multi-epitope vaccines.
UNASSIGNED: Further studies are needed on the development of vaccines in vivo using EgGST alone or in combination with other antigens in the future.
