Upper figure: Alignment map comparing the metallothionein (MT1A) used as bait in our BLAST searches (topmost protein, P04731), and a selection of KRTAPs from the metallothionein-linked set. From second line to bottom. KRTAPs 5–9, 5–1, 5–10, 5–7, 5–8, and 5–3. All have Expect values of lower than 5 × 10^–8 and are thus closely similar to metallothionein MT1A. Lower figure: the highest matched sections on an expanded scale. 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 map was obtained using the COBALT tool at the NCBI
