Symposium Celebrating the 50th Anniversary of Discovery of Sigma Factors
The special symposium celebrates the 50th Anniversary of the Discovery of Sigma Factors.
December 5, 2019 | 8:00 am - 5:15 pm | Waksman Institute

Sigma factors, the central players in bacterial transcription and transcription regulation, were discovered by Richard Burgess and Andrew Travers at Harvard and by John Dunn and Ekkehard Bautz at the Waksman Institute of Rutgers University. The discovery was reported in a joint paper by the Harvard and Rutgers groups in 1969 (Nature 221:43, 1969). The discovery was the starting point for the discovery of promoters, general transcription factors, mechanisms of transcription initiation, and mechanisms of transcription regulation in all organisms, from bacteria through humans. In addition, the discovery was a starting point for the development of expression vectors, protein overproduction, and the biotechnology industry,
