CRISPR-based replication interference system for p15A plasmid copy number control, RNA II site

This composite part uses a CRISPR-based DNA replication interference system for the copy number control of the p15A plasmid. The dCas9 is expressed in an inducible manner with a ssrA degradation tag fused to its C-terminal to minimize the basal expression. The sgRNA has a 20-bp complementary sequence with the template strand of replication activator (RNA II) in p15A origin. However, it shows no effect for some unknown reasons.
