Title: Expression, purification and crystallization of a novel nonstructural protein VP9 from white spot syndrome virus.

Abstract

The nonstructural protein VP9 from white spot syndrome virus (WSSV) has been identified and expressed in Escherichia coli. To facilitate purification, a cleavable His{sub 6} tag was introduced at the N-terminus. The native protein was purified and crystallized by vapor diffusion against mother liquor containing 2 M sodium acetate, 100 mM MES pH 6.3, 25 mM cadmium sulfate and 3% glycerol. Crystals were obtained within 7 d and diffracted to 2.2 Angstroms; they belonged to space group P2{sub 1}2{sub 1}2{sub 1}, with unit-cell parameters a = 74.13, b = 78.21, c = 78.98 Angstroms and four molecules in the asymmetric unit. The selenomethionine-labeled protein produced isomorphous crystals that diffracted to approximately 3.3 Angstroms.
