Amino acid alignment of the 2′-deoxyribosyltransferase of Lactobacillus species, Ureaplasma and B. burgdorferi BB0426. A. Alignment of Lactobacillus helveticus DRTase I active site residues (indicated by shaded boxes) and the catalytic residue unique to DRTase II (asterisk) (Anand et al., 2004) with the sequences of BB0426 and some other members of Pfam 05014 (Finn et al., 2006). B. Spatial arrangement of amino acid residues involved in deoxynucleoside binding with an dAdo molecule shown in bold (Anand et al., 2004).
