Conjugative sgRNA-dCas9 system
This dCas9 is a codon optimized version of BBa_K1150000 for expression in E. coli. Together with a single guide RNA (sgRNA), the protein can be used for silencing of specific target genes. dCas9 is the inactive form of the endonuclease Cas9. In contrast to Cas9, dCas9 does not cleave the DNA. Instead, it sterically blocks the elongation of transcription as a result of the sgRNA-DNA interaction. This will only repress the expression of the target gene thus avoiding the destruction of the gene. [1]
The dCas9 is asembled with the constitutive active promoter BBa_J23100, an RBS BBa_B0034 and a terminator BBa_B0010.
