| Source name |
Microorganism
|
| Organism |
Sulfolobus islandicus |
| Characteristics |
genotype: DpyrEF DlacS
developmental stage: Log-phase cells supplied with arabinose and grown shaking
strain: REY15A
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
To prepare the material for 3C-seq library construction, cells were crosslinked, permeabilized, and treated with AluI. The DNA was then subjected to proximity ligation, crosslink reversal, and phenol extraction followed by isopropanol precipitation. Libraries were constructed using NEBNext Ultra DNA Library Prep Kit for Illumina.

| Data processing |
3C-seq reads were mapped to the genome of S. acidocaldarius DSM639 (GenBank ID: CP000077.1) or S. islandicus REY15A (GenBank ID: CP002425.1) using HiC-Pro version 2.9.0 (Servant et al., 2015) with default parameters. The genomic coordinates of each Sulfolobus species were re-defined so that they started from the first base of the AluI site in the original definition. Valid read were used to generate raw contact matrices. The intra-bin ligations were discarded by setting the values on the corresponding diagonal to zero. The raw contact matrices were iteratively corrected with MAX_ITER = 500 (and FILTER_LOW_COUNT_PERC = 0.01 for S. islandicus) to generate normalized contact matrices.
To calculate Transcripts Per Million (TPM), RNA-seq reads from each biological replicate were mapped in a strand-specific manner using Salmon version 0.8.2 (Patro et al., 2017). When gene expression was quantified at the operon level, reads were mapped to operons predicted by Operon-mapper (Taboada et al., 2018).
