Viral protein 2 (VP2) from infectious bursal disease virus and its precursor polyprotein (N-VP2-VP4-VP3-C), in the absence of their native N-terminal region (19 amino acids), required fusion of yeast presequences for their stable synthesis in Saccharomyces cerevisiae [Jagadish et al., Gene 95 (1990) 179-186]. Restoration of the missing 19 aa resulted in stable synthesis of VP2, indicating the significance of the N-terminal region in protein stability.
传染性法氏囊病病毒的病毒蛋白2(VP2)及其前体多聚蛋白(N-VP2-VP4-VP3-C),在没有其天然N端区域(19个氨基酸)的情况下,需要与酵母前导序列融合才能在酿酒酵母中稳定合成[Jagadish等人,《基因》95(1990)179-186]。缺失的19个氨基酸的恢复导致VP2的稳定合成,表明N端区域对蛋白质稳定性的重要性。
