    • The present invention discloses the isolation and use of a specific bacterial promoter region suitable for use in constructs for the high level production of heterologous proteins. This promoter is derived from the bacterial gene encoding for alcohol dehydrogenase, in particular the alcohol dehydrogenase genes isolated from the thermophilic bacterial strain T. brockii and the mesophilic bacterial strain Clostridium beijerinckii. It is now disclosed that using either the intact promoter region or certain specific fragments consisting of at least a 88 bp DNA sequence in the upstream untranslated region of the bacterial alcohol dehydrogenase gene, operatively linked to the nucleic acid sequences encoding a heterologous protein, and insertion into a DNA plasmid or any other suitable vector system, heterologous genes can be expressed in high levels in host cells. Heterologous proteins or peptides can be expressed constitutively at high levels. The proteins are obtained in their active folded form.
    • 本发明公开了分离和使用适用于高产量异源蛋白质的构建体的特异性细菌启动子区域。 该启动子源自编码醇脱氢酶的细菌基因,特别是从嗜热细菌菌株T. brockii和嗜温细菌菌株Clostridium beijerinckii分离的醇脱氢酶基因。 现在公开的是,使用完整启动子区域或由细菌醇脱氢酶基因的上游非翻译区域中至少88bp DNA序列组成的某些特异性片段,与编码异源蛋白质的核酸序列可操作地连接,并插入 进入DNA质粒或任何其他合适的载体系统中,异源基因可以在宿主细胞中以高水平表达。 异源蛋白或肽可以以高水平组成型表达。 以活性折叠形式获得蛋白质。
