Extended Data Fig. 1: Phylogenetic analysis of oligonucleotide cyclases (CD-NTase) and their CBASS types.
From: Diversity and classification of cyclic-oligonucleotide-based anti-phage signalling systems

The phylogenetic tree of all cyclases, as depicted and colored in refs (5 and 8) is presented in the center. Each clade is then expanded and presented in the periphery as a circular tree to increase resolution. Outer ring depicts the effector type; middle ring depicts the system type. Numbers next to each clade represent the bootstrap value for that node in the central tree.
