    • The present invention relates to synthesis of HBSAg in yeast. Yeast expression vectors comprising a yeast promoter, ADH1, have been constructed. The region of the HBV genome coding for the S-protein, excluding a possible 163 amino acid presequence, has been transferred to the yeast expression vector. Using the described yeast vector, the successful synthesis of HBSAg by yeast has been achieved. The product is antigenic (reactive with anti-HBSAg), and a substantial portion is found associated with particles identical in electron microscopic appearance to those found in the serum of HBV-infected patients and in Alexander cells but having a smaller particle size diameter. The HBSAg synthesized by yeast has identical sedimentation behavior to purified, naturally occurring HBSAg particles purified from Alexander cells as measured by sucrose gradient sedimentation. The present invention demonstrates synthesis and assembly of a higher ordered multi-component structure resulting from expression of a heterologous DNA coding segment in a microorganism.
    • 本发明涉及酵母中HBSAg的合成。 已经构建了包含酵母启动子ADH1的酵母表达载体。 编码S蛋白的HBV基因组区域(不包括可能的163个氨基酸的前序列)已被转移到酵母表达载体中。 使用描述的酵母载体,已经实现了酵母成功合成HBSAg。 该产物具有抗原性(与抗HBSAg反应),并且发现大部分与电子显微镜外观相同的颗粒与HBV感染患者和亚历山大细胞血清中发现的颗粒相关,但具有较小的粒径直径。 由酵母合成的HBSAg与通过蔗糖梯度沉降测量的从亚历山大细胞纯化的天然存在的HBSAg颗粒具有相同的沉淀行为。 本发明证明了通过在微生物中表达异源DNA编码区而产生的更有序的多组分结构的合成和装配。
