Alignment of the amino-acid sequences of (top line) KRTAP17-1 and (bottom line) metallothionein MT1A. (The colour coding here is the “Column Quality score –Protein”, which assigns scores to residues based on how well a particular residue agrees with the others in the column (grey high to red low). The Expect value for the sequence similarity between these two proteins is 7 × 10^–6
