Figure 2

Multiple sequence alignment of abPPO4 (UniProt K9I869), aoTYR (UniProt B8NJ95) and abPPO3 (UniProt C7FF04). Colour code for secondary-structure elements: α-helices, blue tubes; β-strands, green arrows; loops, red arrows; hydrogen-bonded turnovers, TT. Colour code for highlighted residues: copper-binding histidines, orange; conserved tyrosinase motifs, yellow; mutations discerning abPPO4 K9I869 from abPPO4 C7FF04, purple; putative transmembrane anchor (Ala569–Ala591), raspberry; acetylated N-terminus, green.
