Source name |
Bacteria
|
Organism |
Staphylococcus aureus subsp. aureus USA300 |
Characteristics |
bacterial strain: USA300_FPR3757 mutation in strain: None treatment: None
|
Treatment protocol |
Cells were treated with 10 µM ferric ammonium sulfate or left untreated.
|
Growth protocol |
An individual bacterial colony was picked off a plate and grown overnight in tris minimal succinate (TMS) supplemented with 0.4 µM hemin. Cells were sub-cultured to a starting OD600 of 0.01 in iron restricted TMS supplemented with hemin and 1.5 µM transferrin. Cells were grown until mid-log phase at which point cells were treated with 10 µM ferric ammonium sulfate or left untreated for 1 hour before cells were harvested.

Extracted molecule |
total RNA |
Extraction protocol |
To extract RNA from frozen S. aureus and hemB S. aureus, cell pellets were washed with TE buffer (pH 8.0) and re-suspended in a Tris-HCl mixture with 1 mg/mL lysostaphin (pH 7.5) to lyse for 1 hour at 37°C. RNA was extracted using an AurumTM Total RNA Mini Kit (BioRAD #7326820). RNA samples were processed by the Microbial Genome Sequencing Center in Pittsburgh, PA. Ribosomal RNA (rRNA) was depleted (Qiagen FastSelect5S/16S/23S) and cDNA libraries were generated (Qiagen Total Stranded RNA). cDNA libraries were sequenced using NextSeq 550 using a 75bp x 8bp x 8bp setup.

Data processing |
Sequencing reads were mapped to the reference S. aureus USA300 FPR3757 genome in Geneious Prime 2020.1.2 (https://www.geneious.com). Expression analysis and comparisons were performed using DESeq2 (Love MI et al Genome Biol 2014). Genome_build: Staphylococcus aureus USA300_FPR3757 Supplementary_files_format_and_content: xlsx file format, contains RPKM values and calculated differential expression, fold change and p-values for every transcript. Supplementary_files_format_and_content: The processed data file contains all replicates combined and the calculations of differential expression/fold changes are based on the comparison with the appropriate control group. Each sheet is named after the corresponding comparison.
