Figure 3.
Fig. 3. Multiple alignment of conserved regions of the
MJ0577 superfamily showing four sequence motifs. It was
constructed by using PSI-BLAST (38) followed by CLUSTALW (39).
The first column shows the protein identifier with the letters
designating the organism code and the subsequent numbers
designating the gene. Organism codes: MJ, M. jannaschii; MTH,
Methanobacterium thermoautotrophicum; AF, Archaeoglobus
fulgidus; BS, Bacillus subtilis; AQ, Aquifex aeolicus. Conserved
residues are shaded. The black boxes below the sequence indicate
conserved residues contacting ATP (A: adenine; R: ribose; P:
phosphate; D: dimer interface).  -helices
and  -strands are
represented by brackets above the sequences. * at the C terminus
designate those sequences with tandem homologs of MJ0577.
Percent identities between the sequences are at far right.
