摘要

The Escherichia coli tet-repressor (TetR) op- erator system was used to develop a variation of the yeast two-hybrid assay in which disruptions of protein-protein interactions can be identified by a positive selection. This assay, designated the "split-hybrid system," contains a two- component reporter. The first component contains LexA binding sites upstream of the TetR gene and the second contains TetR operator binding sites upstream of HIS3.
