Part:BBa_K2457006

Cas9 device + Optimized sgRNA

This BioBrick is composed by BBa_K2457000 (AraC + pBAD), BBa_K2457001 (Cas9) and BBa_K2457002 (simple guide RNA). Which AraC + pBAD regulates the Cas9 expression through your repressor and your inductor: Glucose and L-Arabinose, respectively. Cas9 is a protein that with the assistance of sgRNA cleaves a target-site in the bacterial genome. This construction was developed by Amazonas_Brazil team to be a fundamental part of the CRISPeasy toolbox, divided in CRISPReasy-out and CRISPReasy-in.

CRISPeasy-out is a standardized knock out approach that aims to turn the current method in an easier way to engineer the bacterial genome by Non-Homologous End Joining (NHEJ).

CRISPeasy-in is a standardized knock-in approach that aims to turn the current method in an easier way to insert a donor template into the bacterial genome by Homology-Directed Repair (HDR).
