Problem statement: Recombinant-based approaches are mostly focused on genetic modification of allergens to produce molecules with reduced allergenic activity and conserved antigenicity, such as hypoallergens. Recombinant allergens represent promising tools for diagnosis and therapy of type I allergy. This approach was probably feasible with every allergen with known amino acid sequence. Approach: The primary aim of this study was to determine the consensus epitope from twenty homologous protein sequences of Ory S1 allergenic protein sequence from Oryza sativa (indica group) pollen. Molecular modeling calculations had been used to investigate the allergenic protein models for the epitope. Results: Oryza sativa (japonica), Phleum pratense, Poa pratensis, Holcus lanatus, Lolium perenne, Triticum aestivum, Dactylis glomerata and Zea mays were found more closely related (alignment score 1145-812) among all the homologs and investigated further. The major binding pocket comprised an area of 604.5
