Figure 2From: Two C or not two C: recurrent disruption of Zn-ribbons, gene duplication, lineage-specific gene loss, and horizontal gene transfer in evolution of bacterial ribosomal proteinsPhylogenetic tree, conserved gene context and multiple alignment of L31 ribosomal proteins. Designations are as in Figure 1. Gene name abbreviations: Rho, transcription termination factor Rho; prfA, peptide chain release factor 1; priA, primosomal protein N'; L31, S9, S12, L36, ribosomal proteins. A partial multiple alignment of L31 protein sequences is shown on the right (the complete multiple alignment used for the tree construction contained 96 positions).Back to article page
