E-GEOD-35826 - ChIP-chip of LeuO, H-NS and RNA Polymerase (RNAP) in Salmonella enterica serovar Typhimurium strain SL1344
Released on 16 February 2012, last updated on 2 May 2014
Salmonella enterica subsp. enterica serovar Typhimurium
The LysR family transcription factor LeuO is believed to antagonize the global repressor H-NS. ChIP-on-chip analysis of LeuO, H-NS and RNAP binding to the Salmonella enterica serovar Typhimurium chromosome demonstrated a high degree of overlap between LeuO and H-NS regulated genes. Furthermore LeuO binding was associated with RNA polymerase recruitment, indicating a role for LeuO in activating transcription.
