dCas9: Expression cassette under a xylose inducible promoter

dCas9 or ‘dead’ cas9 is a mutated version of Cas9 that has lost its endonuclease activity - it no longer cuts double stranded DNA, instead simply binding to it. This means it can function as a repressor after complexing with sgRNA and the sgRNA-target site. dCas9 contains mutations in the RuvC1 and HNH nuclease domains; these changes are what bestow this modified Cas9 with it’s ability to bind DNA instead of cleaving it (Lei S. Qi, 2013). It has a Xylose Inducible Promoter BBa_K1323014 and a sodA RBS BBa_K1323022. The illegal sites have been removed, and the sequence was codon optimized for expression in S. epidermidis using JCat software.

This part was DNA-Synthesized.
