The results indicate that the overall rate constant of P700 + reduction is determined by the rate of electron transfer between the copper and P700 + and confirmed that in ViVo there is a preformed complex between plastocyanin and photosystem I.

Plastocyanin is a copper-containing protein involved in electron-transfer. Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. But, plastocyanin is a small water-soluble blue-copper protein that accepts a pair of electrons from the cytochrome b 6 f complex and passes it to photosystem I in the thylakoid space.

Plastocyanin — is an important copper containing protein involved in electron transfer. The cytochrome b 6 f complex (plastoquinol—plastocyanin reductase; EC 1.10.99.1) is an enzyme found in the thylakoid membrane in chloroplasts of plants, cyanobacteria, and green algae, that catalyzes the transfer of electrons from plastoquinol to plastocyanin.
