From: CRISPR-Cas systems are present predominantly on mobile genetic elements in Vibrio species
A Tn7-like transposon carrying a type I-C CRISPR-Cas system in V. navarrensis. a The type I-C CRISPR-Cas system is present within a mini type I-F-carrying Tn7-like transposon in V. navarrensis ATCC 51183 that is absent in V. navarrensis 08–2426. b Type I-C cas genes and CRISPR repeat in V. navarrensis ATCC 51183. c PAM identified using protospacer sequences. d A neighbor-joining tree of Cas8c from all of the type I-C systems identified. e Type I-C system in V. cidicii 1048–83 was inserted at ATY37_RS07420 relative to strain 2538–88 that lacked the region. Gene comparisons were constructed in Easyfig and gray scale bars indicates nucleotide homology. The core genes are colored in black, Tn7-like transposon and other transposase genes are in pink. Black diamonds in the CRISPR represent direct repeats and colored boxes represent spacers. Blue inverted triangles represent right end and left end attTn7 insertion sites
