FIG. 5.

Frequency of residues within the tryptophan-containing short repeat domains. To generate the frequency histogram, the BSA5-derived amino acid sequence data were used. There were 21 tryptophan residues, 19 of which were in the short conserved motifs. The letters within the bars indicate the amino acid residues. The sections of the bars labeled “others” could include up to four different residues.
