Sample GSM2690568 Query DataSets for GSM2690568
Status Public on Sep 13, 2018
Title GapR_2hr_g60
Sample type SRA
Source name Caulobacter crescentus NA1000
Organism Caulobacter vibrioides NA1000
Characteristics growth stage: exponential phase
genotype: delta-gapR Pxyl-gapR
media: PYE + 0.2% glucose
growth treatment: grown 2hr in 0.2% glucose, 60 mins post synchrony in 0.2% glucose
Growth protocol Caulobacter crescentus was grown to OD 0.2-0.4 before treatment or harvest
Extracted molecule genomic DNA
Extraction protocol Libraries were constructed by end repairing DNA with T4 DNA polymerase (NEB), T4 PNK (NEB), and Klenow large fragment (NEB). 3’ overhangs were added with Klenow (3'→5' exo-) (NEB). Y-shaped Illumina adapters were ligated onto the DNA, and libraries were amplified with either Phusion (NEB) or Kapa HiFi Polymerase (Kapa Biosystems). Libraries were size selected to be 250-600 bp.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description gDNA
Cells were lysed with lysozyme and SDS, and proteins were removed by Proteinase K. CTAB was added and DNAs were extracted by phenol:chloroform:isoamyl alcohol and precipitated. DNA was sheared to 300-800 bp fragments using a Bioruptor Plus sonicator (Diagenode). RNase A (Qiagen) was added and the fragments were electrophoresed, and 300-600 bp fragments were size selected, purified with Gel Extraction Kit (Qiagen), and resuspended in 50 µL EB. Sequencing reads were aligned to NC_011916.1 offset by 1 MB.
Data processing Reads were aligned to Caulobacter NC_011916.1 (NA1000) with bowtie (single-end reads) or bowtie2 (paired end reads) allowing for 1 mismatch
Bowtie alignments were converted to wiggle files by mapping the center of each read.
Genome_build: NC_011916.1
Supplementary_files_format_and_content: wig files were generated using custom python scripts, tab delimited files, first column represents genome position, second column represents value of position
