Fig. 6. Alignment of the proposed MybE DNA-binding domain. (A) Alignment to plant SHAQKY proteins. ClustalW was used to align the MYB domain of MybE to four plant MYBs: Arabidopsis CCA1 and three others of unknown function, identified by their Accession Numbers. The asterisks indicate two tryptophan residues that are highly conserved in all Myb domains. MybE and the plant proteins lack a third, otherwise conserved tryptophan residue and this is replaced by a `SHAQKY'-related sequence. (B) Alignment of Dictyostelium SHAQKY proteins The Dictyostelium proteins were identified in genome database and aligned using ClustalW.
