Hybrid Synthetic Promoters in Saccharomyces cerevisiae Built on Foreign Promoter Sequences
摘要
Traditionally, hybrid promoters are constructed, in Saccharomyces cerevisiae, by joining the core region and the upstream activating sequences from different native promoters. Here, we describe a new design that makes use of the core promoters from foreign organisms: viruses, humans, and the yeast Schizosaccharomyces pombe. With this approach, we realized a library of 59 new constitutive promoters that span over nine folds in gene expression.
