Fig. 4: CRISPR-Cas systems in Vampirococcus.
From: Reductive evolution and unique predatory mode in the CPR bacterium Vampirococcus lugosii
a Genes in the two systems encoded in the Vampirococcus lugosii genome, elements common to the two systems are highlighted in blue. b Maximum likelihood phylogenetic tree of the Cas1 protein encoded in the class II type V system, numbers at branches indicate bootstrap support.
