Addgene inc broad host range conjugative plasmid prk24
Plasmid artificial modification–assisted conjugative engineering (PACE). Methylation-matched plasmids produced in engineered E. coli donor strains are transferred to Geobacillus recipients via <t>pRK24-mediated</t> conjugation. While host-specific methylation enables restriction evasion, intracellular defense systems limit plasmid establishment in wild strains. b, Architecture of the native Type II-C CRISPR–Cas system (GeoCas9EF) adapted for genome editing. A 21-bp spacer sgRNA cassette targets genomic loci adjacent to a protospacer-adjacent motif (PAM). c, Sequence logo of the preferred PAM recognized by GeoCas9EF in G. stearothermophilus EF60045, indicating a consensus 5’-NNNNCAAA- 3’ motif. d, CRISPR-mediated genome editing strategy. A conjugative plasmid carrying GeoCas9EF, sgRNA, and homologous repair arms enables genome modification via Cas9-induced cleavage and homologous recombination. Single-crossover (SCO) intermediates are resolved into double-crossover (DCO) mutants or false positives. Promotor optimization for Cas9 expression in strain SJEF4-2 is shown. e, PCR validation of representative gene deletions generated by CRISPR editing in SJEF4-2 and EF60045, targeting pyrimidine biosynthesis loci (e.g., pyrR and pyrFE ). Expected fragment sizes are indicated. f, Transformation efficiencies following sequential removal of endogenous defense systems. In EF60045 and SJEF4-2, deletion of native plasmids and non-canonical defense modules, including Wadjet II, BREX, CBASS, Gabija, Abi, and SspBCDE, dramatically increased electroporation efficiency (CFU µg ¹ DNA) and conjugation efficiency (transconjugants per recipient), revealing these systems as dominant barriers to genetic domestication.
