Fig. 3. Amino acid sequence alignments. (A) Alignment of DimB with
DimA. The sequences of the entire DimB protein and a C-terminal proximal
fragment of DimA, DimA*, were aligned using Clustal W. The arrowed
line over part of the sequence shows the positions of the proposed DNA-binding
and dimerisation domains. (B) Partial alignment of DimB with DimA and
other bZip proteins. The indicated segments of the proteins were aligned using
Clustal W and the arrowed lines over the sequences show the positions of the
DNA-binding and dimerisation domains. Closed diamonds indicate basic residues
and open diamonds indicate leucine residues. The other proteins in the
alignment are Dictyostelium DimA and human CREB, AP1 and ATF6A.
