Studies from Karl-Franzens University Graz reveal new findings on DNA research

Published in Proteomics Weekly, September 3rd, 2007

Investigators publish new data in the report "GroEL plays a central role in stress-induced negative regulation of bacterial conjugation by promoting proteolytic degradation of the activator protein TraJ." According to a study from Graz, Austria, "Transcription of DNA transfer genes is a prerequisite for conjugative DNA transfer of F-like plasmids. Transfer gene expression is sensed by the donor cell and is regulated by a complex network of plasmid-and host-encoded factors."

"In this study we analyzed the effect of induction of the heat shock regulon on transfer gene expression and DNA transfer in Escherichia coli. Raising the growth temperature from 22 degrees C...
