Abstract: The present invention pertains to single plasmid systems comprising sequences encoding programmable proteins, one or more guides, optionally donor polynucleotides, and optionally anti-CRISPR molecules, for gene editing. These plasmid systems allow for genomic engineering of bacterial strains that are difficult to transform and increase the efficiency of genomic engineering in tractable strains. Additionally, the single plasmids can be configured to provide for the transformation of a number of different bacterial strains using the same plasmid.
