Amino acids and the disulfide bond are related to antioxidant activity. The amino acids are indicated by the following colors: cyan (Trp), yellow (Tyr), magenta (CA active center: His95, His97 and Gln114), blue (Cys28-Cys187 disulfide bond) and green (selected surface hydrophobic amino acids: Ala, Ile, Leu, Phe, Val, Pro and Gly).
