Sequence analysis of SaCSD1. (a) Coding sequence and amino acid sequence of SaCSD1; (b) Amino acid sequence alignment of CSDs for Sonneratia alba and other species. Triangle denotes copper ion binding sites, asterisk denotes zinc ion binding sites, circle denotes amino acids which form disulphide bonds, arrow indicates changes in the amino acids at the 89th and 94th positions between the plant species belonging to the Poaceae family and other families, and dc represents amino acids involved in dimer contact. Residues that are identical among the sequences are given a black background, and similar residues are in a gray background. The remaining residues are in a white background.
