Analysis of CRISPR‐positive complete genomes and high‐quality assemblies was performed to better characterize the genomic context surrounding the cas gene sets and/or CRISPR arrays. High‐quality assemblies with at least 4 kb flanking the cas gene sets were considered. These regions were annotated by Prokka (https://github.com/tseemann/prokka) (Seemann, 2014 (link)). Synteny was established by either the Mauve algorithm (http://darlinglab.org/mauve/mauve.html) (Darling et al., 2010 (link)) or visual inspection of annotated proteins.
