Comparison of Cu-SOD domains of the oyster CRSPs. At the active site, the red letters on the top lines denote the Cu-binding sites, yellow for the dynamic histidine, blue for Zn-binding sites, and black for mutated Zn-binding sites. The similarity between the four domains of CSRPs ranged from 32–55%, with 35.67% identity and 52.23% similarity to C. albicans SOD5. The identity with Cg-dominin3 was 27%, with a similarity of 34%.
