September 9th, 2008
Researchers detail in 'RpoS, H-NS, and DsrA influence EHEC hemolysin operon (ehxCABD) transcription in Escherichia coli O157:H7 strain EDL933,' new data in Escherichia coli. "Escherichia coli hemolysin, also termed alpha-hemolysin, is a virulence factor for extraintestinal E. coli. Hemolysin operon (hlyCABD) transcription is inhibited by the nucleoid-associated protein, H-NS," scientists in the United States report. "This inhibition is stronger at lower growth temperature. This study investigated transcription of the homologous EHEC hemolysin (enterohemolysin) operon (ehxCABD) in EHEC O157:H7 strain EDL933. We examined the influence of H-NS, the sigma...
