| Source name |
Enriched mRNA
|
| Organism |
Streptococcus pyogenes |
| Characteristics |
strains: Revertant strain
genotype description: RocA deletion strain
genotype: RocA-
|
| Growth protocol |
All GAS strains were grown to an O.D.600 of 0.5
|
| Extracted molecule |
total RNA |
| Extraction protocol |
GAS cultures were incubated with RNAprotect™ (Qiagen) for >5 min at room temperature, pelleted and frozen at -80 °C overnight. Cells were resuspended in RLT-BME and lysed using FastPrep Lysing Matrix B tubes (MP Biomedicals) in FastPrep-24 machine. Samples were processed twice at speed 4 for 15 sec. Total RNA was then isolated using miRNEasy Mini Kit (Qiagen) and eluted in nuclease-free water. Off-column DNase treatments, using DNA-free DNase (Ambion), was performed at 37 °C. The mRNA was then enriched using Ribo-Zero rRNA Removal Kit (Bacteria) to deplete rRNA contamination.
All cDNA libraries were constructed using ScriptSeq™ RNA-Seq Library Preparation Kit (Epicentre) and processed according to manufacturer's protocol.

| Data processing |
CLC Genomics Workbench version 7.5.1 RNA-seq was used for basecalling and aligning the sequence reads to the MGAS315 genome (AE014174.1). Parameters for alignment were set up: Similar fraction=0.8, Length fraction=0.8, Mismatch cost=2, Insertion cost=3, and Deletion cost=3. Normalization of the data was accomplished using the Kal's Z-test with FDR from the total read count.
Genome_build: AE014174.1
Supplementary_files_format_and_content: Excel files containing all coding regions from genome with raw and normalized expression values, RPKM, coding region nucleotide start and stop, Kal's Z-test calculations, and raw and normalized means. The normalized means were used for calcuating transcript fold change between samples.
