Plastocyanin extracted from a Green Alga, Enteromorpha prolifera, has a '''β-sandwich structure'' as a slightly flattened cylinder with approximate dimensions 40 Å × 32 Å × 28 Å . This β-sandwich is composed of two β-sheets (I and II) separated by a hydrophobic core.Turns on the two β-sheets occur between residues 42 to 45 and 47 to 50. | Plastocyanin extracted from a Green Alga, Enteromorpha prolifera, has a '''β-sandwich structure''' as a slightly flattened cylinder with approximate dimensions 40 Å × 32 Å × 28 Å .

Seven strands (1 to 4 and 6 to 8) of the polypeptide backbone have substantial β character and contribute to the β-sheets. The 5 strand has no β character and formed a helical segment. | Seven strands (1 to 4 and 6 to 8) of the polypeptide backbone have substantial β character and contribute to the β-sheets.
