Sequence alignments of C. trachomatis L2 CTL843 and R. prowazekii RP076 SAM transporter. Amino acid sequences were first aligned on a web interface of MAFFT (53) and were subsequently aligned via Clustal W2 to illustrate the similarity. Identical residues are denoted with an asterisk and are highlighted in black boxes. Strongly conserved residues and weakly conserved residues are marked with a colon and a period, respectively, and are displayed in gray boxes.
