Figure 1.

Sequence alignment of DR2204 with the Tt_Ndx2 (Thermus thermophilus HB8; 40% identity), Ec_ADPRaseII (E. coli ORF186; 24% identity) and Ec_ADPRaseI (E. coli ORF209; 21% sequence identity) proteins. Identical residues are shown in white on a red background and similar residues are shown in red on a white background. For the secondary-structure assignment, α-helices are represented as helices, β-strands are represented as arrows and β-turns are marked ‘TT’. This figure was prepared with ESPript (Gouet et al., 1999 ▶). The multiple sequence alignment was performed with CLUSTALW (v1.83) (Thompson et al., 1994 ▶)
