Sample GSM2712355 Query DataSets for GSM2712355
Status Public on Feb 27, 2018
Title TAK1082_pol3L612M_pol2-16
Sample type SRA
 
Source name TAK1082 pol3L612M pol2-16
Organism Saccharomyces cerevisiae
Characteristics strain: pol3L612M pol2-16
Growth protocol Yeast strains were grown to mid log phase (OD600=0.5-1) at 23°C in YPDA medium supplemented with 0.25 mg/ml adenine
Extracted molecule genomic DNA
Extraction protocol DNA was isolated using the MasterPure™ Yeast DNA Purification Kit (Epicentre) without RNase A treatment.
Ribonucleotides were mapped in the genomic DNA using Hydrolytic End Sequencing technique (HydEn-seq) described by Clausen et al., 2015. Briefly, DNA was isolated from exponentially growing yeast (OD600: 0.5 – 1/ ml) with using a kit for genomic DNA isolation from yeast (Epicenter). Libraries for Next Generation Sequencing were prepared with using 1 µg of DNA, which was treated with 20 U of restriction enzyme SbfI-HF (New England Biolabs) at 37o C for 1h. Next DNA was treated under 300 mM KOH at 55o C for 2 hours and precipitated with ethanol. Library were constructed as described in Clausen et al., 2015. Briefly, DNA was denatured for 3 min at 85o C, phosphorylated with 10 U of T4 PNK (#M0236, New England Biolabs) and purified with 1.8 volume of magnetic beads (Magbio). After denaturation for 3 min at 85o C, DNA fragments were ligated with adapter ARC140 over night at 25o C using 10 U of T4 RNA ligase (#M0204, New England Biolabs). This was followed by DNA purification with magnetic beads and the second strand synthesize using 4 U of T7 DNA polymerase (#M0274, New England Biolabs) and ARC76/77 duplex. After DNA purification with magnetic beads, unique indexes were added to DNA fragments using KAPA HiFi HotStart Ready Mix (#KK2602, KAPA Biosystems). The library concentrations and sizes were determined using Bioanalyzer. Libraries were pooled and subject for paired end sequencing with Illumina HiSeq 2500.

Data processing Base calling and generation of FASTQ files performed by Illumina Hiseq standard pipeline
Reads trimmed for adapter sequence using cutadapt 1.12, discarding pairs with one or both reads shorter than 15 nt
Combine technical replicates
Align end 1 to index of oligos used during library prep, exclude successful pairs from further analysis (bowtie 1.2 -k1 -v2)
Align remaining pairs to W303 reference genome, trim single nt from 3' end of reads to allow mapping of 100% overlapping pairs (bowtie 1.2 -m1 -v2 -X10000 -3 1)
Align end 1 of unmapped pairs to W303 reference genome (bowtie 1.2 -m1 -v2)
Retain 5' end only for all single- and paired-end unique alignments, shift 1 base upstream and combine
