Sample GSM3118779 Query DataSets for GSM3118779
Status Public on May 26, 2018
Title wee1-50_delta_mutant 34C Pu-seq
Sample type SRA
 
Source name wee1-50_delta_mutant
Organism Schizosaccharomyces pombe
Characteristics strain: YAK257
genotype/variation: h-, Wee1-50, rnh201::HYG, cdc6L591G ade6-704, leu1-32, ura4-D18
Growth protocol Cells were grown on 34C in YPD media to log phase. For ‘wt’ datasets two strains were used, both strains containing rnh201 deletion together with either polymerase δ (cdc6-L591G) or polymerase ε (cdc20-M630F) mutations. These strains incorporate more rNTPs on the strands synthetized by the mutant polymerase. These sites can be mapped by Pu-seq. For the wee1-50, set2Δ and wee1-50 set2 Δ datasets the two strains also contained these mutations along with rnh201 and cdc6-L591G or cdc20-M630F.
Extracted molecule genomic DNA
Extraction protocol DNA was prepared using the QIAGEN 100/G Genomic-tip. The isolated DNA was then subjected to alkali treatment (0.3 M NaOH, 2h 55°C) which digested the DNA at the positions of rNTP incorporation and also separated the double strands. The resulting ssDNA fragments were size selected on agarose gel (fragments between 300-500bp were isolated).
Polymerase usage sequence (Pu-seq) technique was performed as previously described (Daigaku et al., 2015 and Keszthelyi et al. 2015)
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
 
Description rNTP-pol-d-wee1-50-34C_S7
Data processing library strategy: Polymerase usage sequence (Pu-seq)
The reads were mapped using bowtie2
Origin positions and efficiencies were determined using the tools published and described in detail in Daigaku et al., 2015 and Keszthelyi et al. 2015. with default variables except for the ‘percentile threshold for origins’ option was set to 0.2 = 20th percentile.

Supplementary_files_format_and_content: Bedgraph files contain the position and the efficiency of the origins.
