Figure 1.

Optimal sequence alignment of the second repeat of the DNA-binding domain of Bas1p and repeats in other various Myb family members. Letters on the right refer to the species from which the sequences used for alignment were extracted. Sc, Saccharomyces cerevisiae; Gg, Gallus gallus; Xl, Xenopus laevis; Sp, Schizosaccharomyces pombe; Al, Aspergillus nidulans; Dm, Drosophila melanogaster; Hs, Homo sapiens; Dd, Dictyostelium discoideum; At, Arabidopsis thaliana. The identical and the highly conserved residues in all sequences aligned are marked by the symbols * and ¤, respectively. The conserved cysteine residue (C153 in Bas1p) is boxed. Numbers on the right refer to the position in the protein sequence.
