Phylogenetic analysis of PIWI-domains and organization of the predicted pAgo operons. The ML tree is rooted between the (predominantly) PAZ-domain-containing and PAZ-domain- lacking branches. The RELL bootstrap values are indicated (%) for selected major branches. Color code: gray, Eukaryota; orange, Archaea; blue, Proteobacteria, green, Firmicutes; black, other lineages of bacteria. Each organism is denoted by the full systematic name and the Gene Identifier (GI) number. The PDB ID is indicated for those sequences for which tertiary structure is solved. Sequences of short PIWI proteins (that have lost N-terminal part including PAZ domain) but belong to the branch that consists mostly of full size sequences are indicated by "#" symbol. For those PIWI-domain proteins that are associated with genes encoding a nuclease domain, the domain architectures of the pAgo-associated proteins are shown.
