Fig. 4

Three-dimensional structure of aligned WSSV VP28 envelope protein of BAN_SH_BG-1C_2014 that was taken as representative of isolates collection in 2014 in Bangladesh and PDB id 2ED6. The side chain of Glutamic acid (E) in the reference protein protruded out of the surface portion where the BD isolate contained Glycine (G). The amino acid positioned between the beta-strands seven and eight. The red color in the figure showed the protruded side chain. Paste color and gray color represented the target region (160–170 amino acid) and the rest of the protein. Surface and line style was used to visualize the protein and side chain of glutamic acid
