    • There are described a number of plasmid vectors suitable for the expression of genetic material, at various levels in yeasts. The plasmids each comprise a yeast selective marker, a yeast replication origin and a yeast promoter positioned relative to a unique restriction site in such a way that expression may be obtained of a polypeptide coding sequence inserted at the restriction site. The promoters used are derived from the 5' region of a gene coding for a yeast glycolytic enzyme e.g. phosphoglycerate kinase (PGK), or from the 5' region of the yeast TRP1 gene. In one Example a plasmid contains a promoter derived from both the 3' and 5' regions of the PGK gene. The replication systems used involve the yeast 2.mu. replication origin or an autonomous replicating sequence (ARS) stabilized with an ARS stabilizing sequence (ASS). The replication systems allow for a choice of high or low copy number per cell. The promoter sequences allow for a choice of high or low expression level. A kit including vectors having a combination of these alternative features is described. Yeast expression vectors including a gene for coding for human interferon-.alpha. are described.
    • 描述了许多适于在酵母中各种水平表达遗传物质的质粒载体。 质粒各自包含酵母选择性标记,酵母复制起点和相对于独特的限制性位点定位的酵母启动子,使得可以获得插入限制性位点的多肽编码序列的表达。 所用的启动子来源于编码酵母糖酵解酶的基因的5'区域, 磷酸甘油酸激酶(PGK),或来自酵母TRP1基因的5'区。 在一个实施例中,质粒含有源自PGK基因的3'和5'区两者的启动子。 所使用的复制系统涉及用ARS稳定序列(ASS)稳定的酵母2微复制起点或自主复制序列(ARS)。 复制系统允许每个单元格选择高或低拷贝数。 启动子序列允许选择高或低表达水平。 描述了包括具有这些替代特征的组合的载体的试剂盒。 描述了包含用于编码人类干扰素-α的基因的酵母表达载体。

    • An upstream activator sequence derived from the yeast PGK gene. The upstream activator sequence is contained in the 5' region of the yeast PGK gene between nucleotides -324 and -455. The upstream activator sequence has synthetic linkers attached to either end to facilitate attachment to a vector. Vectors including the upstream activator sequence and a heterologous promoter sequence are described. The upstream activator sequence is used in a method for increasing the expression level of a yeast expression vector.
