Figure 1

Sequence alignment of part of the N-terminal regions of archaeal-type AspRS proteins. (Upper) ND-AspRSs. (Lower) D-AspRSs. Positions with >90% identity are red, and those with >90% similarity are blue. Amino acids in the two positions that differ between the two groups are highlighted in gray, and shown in white for the ND-AspRSs, and in yellow for the D-AspRSs. (Lower) T. kodakaraensis AspRS secondary structure elements (ref. 14) are indicated; only the C-terminal part of β-strand 4 (′β4) and the N terminus of β-strand 5 (β5′) are shown. Sequences not referenced earlier (ref. 15) are listed with GenBank accession numbers.
