Plasmids were transformed with high efficiency using the Frozen-EZ Yeast Transformation II Kit in the construction of synthetic yeast promoters. Researchers showed that decreasing nucleosome affinity correlated with increasing promoter strength and expression levels higher than native species.Curran KA, et. al. (2014) Design of synthetic yeast promoters via tuning of nucleosome architecture. Nat Commun. 5:4002.
The Frozen-EZ Yeast Transformation II Kit was used to integrate various TEF1 promoter mutants upstream of a gene in Saccharomyces cerevisiae. Efficient transformation allowed comparison of gene activity and, therefore, determination of promoter strength.Nevoigt, E., et al. (2006) Engineering of promoter replacement cassettes for fine-tuning of gene expression in Saccharomyces cerevisiae. Appl Environ Microb, 72(8): 5266-5273.
