Abstract
We have developed a method with prokaryotic organisms that uses randomized libraries of zinc finger-containing artificial transcription factors to induce phenotypic variations and to identify genes involved in the generation of a specific phenotype of interest. Combining chromatin immunoprecipitation experiments and in silico prediction of target DNA binding sequences for the artificial transcription factors, we identified ubiX , whose down-regulation correlates with the thermotolerance phenotype in Escherichia coli . Our results show that randomized libraries of artificial transcription factors are powerful tools for functional genomic studies.Keywords
