Figure 1

Multiple alignment of the polygalactosaminidase family that includes MJ1477, the alleged archaeal CysRS. Proteins are denoted by their gene name, followed by their species abbreviations and GenBank identifier (GI) numbers. The coloring reflects the 100% consensus. The consensus abbreviations and coloring scheme used in this and subsequent figures are as follows. Hydrophobic residues (h; LIYFMWACV) and aliphatic (l;LIAV) residues are shaded yellow. Colored magenta are alcohol (o; ST), charged (c; KERDH), basic (+; KRH), acidic (-; DE), and polar (p;STEDRKHNQ) residues. Small (s; SAGDNPVT) residues are colored green and big (b; LIFMWYERKQ) residues are shaded gray. The hydrophobic residues of the signal peptide are highlighted in yellow. In the Secondary Structure line, H indicates a helix and E indicates extended conformation (b strand). Aqa, Aquifex aeolicus; Dr, Deinococcus radiodurans; Mj, Methanococcus jannaschii; Pa, Pseudomonas aeruginosa; Ps, Pseudomonas species; Scoe, Streptomyces coelicolor; Strgi, Streptomyces griseus; Tm, Thermotoga maritima.
