Abstrakt: The selected dodecapeptide (1)DRALYGPTVIDH(12) from a phage-displayed peptide library and the crystal structure of the envelope glycoprotein B (Env gB) from Herpes Simplex Virus type 1 (HSV-1) led us to the identification of a new discontinuous epitope on the Bovine herpesvirus type 1 (BoHV-1) Env gB. In silico analysis revealed a short BoHV-1 gB motif ((338)YKRD(341)) within a epitope region, with a high similarity to the motifs shared by the dodecapeptide N-terminal region ((5)YxARD(1)) and HSV-1 Env gB ((326)YARD(329)), in which the (328)Arg residue is described to be a neutralizing antibody target. Besides the characterization of an antibody-binding site of the BoHV-1 Env gB, we have demonstrated that the phage-fused peptide has the potential to be used as a reagent for virus diagnosis by phage-ELISA assay, which discriminated BoHV-1 infected serum samples from negative ones.
