(Submitter supplied) CRISPR arrays form the physical memory of CRISPR adaptive immune systems by incorporating foreign DNA as spacers that are often AT-rich and derived from viruses. As promoter elements such as the TATA-box are AT-rich, CRISPR arrays are prone to harbouring cryptic promoters. Sulfolobales harbor extremely long CRISPR arrays spanning several kilobases, a feature that is accompanied by the CRISPR-specific transcription factor Cbp1. more...

(Submitter supplied) Chromatin proteins competes with the transcription machinery for access to genomic DNA and suppress cryptic promoters. CRISPR arrays form the physical memory of CRISPR adaptive immune systems. The incorporation of virus-derived AT-rich DNA into CRISPR arrays renders them prone to harbouring cryptic promoters. Sulfolobales feature extremely long CRISPR arrays spanning several kilobases as well as a CRISPR-specific chromatin protein termed Cbp1. more...

(Submitter supplied) Transcriptome sequencing was carried out on an Illumina HiSeq platform to investigate the activation of CRISPR-Cas and DNA repair systems by Csa3a in Sulfolobus islandicus Rey15A. We compared the differently expressed genes in Sulfolobus islandicus Rey15A strain with csa3a overexpression vs. Sulfolobus islandicus Rey15A strain carrying an empty expression vector, cas1 deletion strain with csa3a overexpression vs. more...
