In larvae and juveniles, mortality is up amount 100%. The capsid protein of the DGNNV form virus-like particles (VLPs) that were expressed in Escherichia coli. So far, Crystals of VLPs diffracted X-rays to ~7.5 Å resolution (Luo and Lin, 2014). In this study, VLPs purified in phosphate buffer were cross-linked with DSS grown to crystals of higher resolution of diffracted X-rays. Among poly-His tagged VLPs and point-mutation, C338C6H can not form crystals while N25R29A mutant resulted in bigger size. VLPs for studies of DGNNV VLPs protein structure and function.
