The characterization of high-availability sites within motifs.

<p>(<b><i>a</i></b>) The distribution of the pentat availability scores within motifs and random fragments. (<b><i>b</i></b>) The rank order analysis of the amino acid composition of full sequences, motifs, and high-availability areas of pentats, quartets, and triplets within motifs. The rank order distance (ROD) scores are shown beside the horizontal bars. The numbers at the top of each amino acid indicate the rank difference from the full sequences.</p>
