Figure 1. Multiple alignment of the editing domain of AlaRS and
ThrRS enzymes. Residues involved in coordination of the zinc ion
(red) and highly conserved residues (yellow) are indicated. The
secondary structure elements in the crystal structure of PH0574
(above) and ecThrRS (below) are shown in the alignment. GenBank
accession numbers given in parentheses are PH0574 (NP_142539),
mbAlaX (ZP_00296079), pfAlaRS (NP_577999), ecAlaRS (NP_417177),
saThrRS (NP_646443, PDB ID: 1NYR), ecThrRS (NP_416234, PDB ID:
1QF6).
