Figure 3From: Casposons: a new superfamily of self-synthesizing DNA transposons at the origin of prokaryotic CRISPR-Cas immunityPhylogeny of protein-primed B family DNA polymerases. Clades that are only distantly related to the casposon-encoded proteins were collapsed. The tree is rooted with phi29-like bacteriophages of the Podoviridae family. Numbers at the branch points represent RELL (resampling of estimated log-likelihoods)-like local support values calculated by FastTree.Back to article page
