ID Plasmid Purpose
89232pCsy_complexPlasmid contains the genes Csy1, Csy2, Csy3, Csy4, cloned as a polycistronic operon from bacterium Pseudomonas aeruginosa PA14. Csy3 includes an N-terminal 6his tag and TEV protease cleavage site
89233pAcrF1Plasmid contains the gene for anti-CRISPR protein AcrF1 (gene 35 from bacteriophage JBD30), with N-terminal 6his tag and TEV protease cleavage site
89234pAcrF2Plasmid contains the gene for anti-CRISPR protein AcrF2 (gene 30 from bacteriophage D3112), with N-terminal 6his tag and TEV protease cleavage site
89244pCRISPR_DMS3g24Plasmid encodes a synthetic CRISPR containing 7 copies of a single spacer, which targets a region (gene 24) in the genome of bacteriophage DMS3
