E. coli CRISPR I leader sequence
Usage and Biology
- This is the AT-rich leader region of the CRISPR I array in Escherichia coli str. K-12 substr. MG1655. "Identification and characterization of E. coli CRISPR-cas promoters and their silencing by H-NS" (Ü. Pul et al, 2010) characterized a single promoter (Pcrispr1) in this sequence. Transcription is silenced through H-NS binding to the leader sequence. Induction requires anti-silencing, either by protein-independent processes, DNA-binding proteins or other modulatory mechanisms not yet identified.
