Title |
RelA + isoleucine starved rep1 |
Sample type |
SRA |
|
|
Source name |
RelA + isoleucine starved bacterial cells
|
Organism |
Escherichia coli |
Characteristics |
strain/background: MG1655relA::HTF growth condition: isoleucine starved antibody: M2-anti-FLAG
|
Treatment protocol |
Non-starved cultures were collected at OD600=0.2 and isoleucine starved cultures were collected after incubation with 500μg/mL L-Valine for 30 min (samples indicated by +val).
|
Growth protocol |
Bacterial cells were grown in MOPS (morpholinepropanesulfonic acid) minimal medium at 30C supplemented with 0.2% glucose and with all nucleobases (10 µg ml-1 of each).
|
Extracted molecule |
total RNA |
Extraction protocol |
The cells were subsequently UV-C crosslinked and harvested by centrifugation, washed in ice-cold phosphate-buffered saline (PBS) and snap frozen in liquid nitrogen. The pellets were stored at -80C. The HTF tagged proteins were then purified, linkers ligated to crosslinked RNA, cDNA synthesized and DNA libraries generated as described in Winther et al. 2018. Libraries were constructed as per Winther et al. 2018.
