PCY contains a copper atom in its active site. The Cu ion can be in oxidised form (Cu+2) or reduced form (Cu+1). Structural highlights The PCY molecule has an 8-strand β-barrel shape containing an acidic patch and a hydrophobic patch around the His residue in the active site. His and Leu residues are involved in PCY interaction with cytochrome f needed for for the electron transport. 3D structures of plastocyanin Plastocyanin 3D structures
