The amino acid sequences of the envelope (E) protein of four encephalitogenic and five non-encephalitogenic dengue 3 virus strains isolated in Malaysia were determined and compared. Multiple sequence alignment revealed a high degree of similarity in the E protein of the strains suggesting that neurovirulence of these four encephalitogenic strains is not attributed to this protein.
测定并比较了在马来西亚分离出的4株致脑炎型和5株非致脑炎型登革热3型病毒株包膜(E)蛋白的氨基酸序列。多序列比对显示这些病毒株的E蛋白具有高度相似性,这表明这4株致脑炎型病毒株的神经毒力并非归因于该蛋白。
