Dynamic Gene Cluster Comparison in Prokaryotic Genomes

Are you curious about how a gene cluster is conserved across other genomes? Use our web-based Comparative Gene Cluster Viewer (CGCV) to interactively visualize the conservation of your favorite gene cluster against the available Bacterial genomes, via our novel multi-genome browser. Step-by-step instructions are provided in the tutorial page. Our Bacterial sequence repository is synchronized with NCBI GenBank on a nightly basis thus guaranteeing access to the latest sequence data. View the Update Report to see the status of our repository.
