Poly(A) polymerases (PAPs) and tRNA nucleotidyltransferases belong to a superfamily of nucleotidyltransferases and modify RNA 3'-ends. The product of the pcnB gene, PAP I, has been characterized in a few β-, γ- and δ-Proteobacteria. Using the PAP I signature sequence, putative PAPs were identified in bacterial species from the α- and ε-Proteobacteria and from four other bacterial phyla (Firmicutes, Actinobacteria, Bacteroidetes and Aquificae). Phylogenetic analysis, alien index and G+C content calculations strongly su
