Sequence alignment and functional domain prediction of CsPPO sequences in different cultivars. (a) Alignment of amino acid sequences of CsPPO in small- and large-leaf varieties. Black and gray shades indicate sequence conservations of 100% and > 80%, respectively. Sequences were aligned using the ClustalW algorithm. Black lines above the sequences indicate the common central domain of tyrosinase. Red boxes indicate the tyrosinase CuA-binding region HNSWLFFPFHRFYLYFFE and the tyrosinase and hemocyanin CuB-binding region DPIFYGHHANVD. (b) Predicted functional domains on the CsPPO sequences. Squares in different color indicate the position of conserved domain of protein families on the sequences. Purple squares represented two cooper ion binding regions of tyrosinase.
