Sample GSM3503258 Query DataSets for GSM3503258
Status Public on Mar 11, 2019
Title IU1781 WT-TEX-3
Sample type SRA
 
Source name bacterial cells
Organism Streptococcus pneumoniae D39
Characteristics strain: IU1781
treatment: none
genotype: wild type
Growth protocol Strains were grown in Difco Brain Heart Infusion Broth at 37oC in atmosphere of 5% CO2 to an OD620 of 0.15 to 0.2
Extracted molecule total RNA
Extraction protocol RNA was isolated from cells via the Fastprep blue kit (MPBiomedicals)
For samples 1-3, the library was generated by removing DNA by DNase treatment, depleting rRNA with Ribo-Zero rRNA removal kit for gram-positive bacteria, fragmenting RNA reagent (Ambion), removing 5' triphosphates via RNA 5' polyphosphatase, and subsequently utilizing the TruSeq Small RNA library kit. For samples 4-6, the same protocol was used as for Samples 1-3, but prior to RNA 5' polyphosphatase treatment the RNA was treated with Terminator 5'-phosphate-dependent exoribonuclease.
 
Library strategy ncRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2000
 
Description Fragmented rRNA depleted RNA
Data processing For libararies constructed with Samples 1-6, adapters were trimmed using Cutadapt. Trimmed reads were mapped on the Streptococcus pneumoniae D39 (CP000410.1) genome using Bowtie2 version 2.0.6. Aligned reads were visualized in IGV to identify peaks corresponding to small RNAs.
Read coverage was generated from BAM files using a combination of SAMtools, Bedtools, and a custom R script to normalize coverage per million reads or paired-end fragments. Paired reads were filtered so that only properly-paired reads of fragments less than 600 nt were included in coverage counts.
Genome_build: CP000410.1
Supplementary_files_format_and_content: bigWig files, read coverage maps
