Automatic elimination of unnecessary bacterial sequences from yeast vectors.


Most vectors for Saccharomyces cerevisiae are shuttle vectors which can be both propagated and selected in Escherichia coli. The DNA segments, however, which are required for propagation in E. coli are unnecessary and moreover toxic in S. cerevisiae. To delete these harmful DNA fragments from the vector after it is introduced into S. cerevisiae cells, we… (More)
