The aggregation, arrangement and bonding together of a set of components to form the oxygen evolving complex (OEC) of photosystem II on thylakoid membrane. In plants, the photosystem II OEC consists of three extrinsic nuclear-encoded polypeptides: PsbO, PsbP and PsbQ; and protects the CaMn4 cluster bound to D1 and CP43 proteins. The aggregation, arrangement and bonding together of a set of components to form a photosystem II complex on thylakoid membrane. In plants, the photosystem II complex consists of over 20 polypeptides encoded by either nuclear or chloroplast genome. The light reactions of photosynthesis, which take place in photosystems II and I. Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH. NADPH generated from light reactions is used in sugar synthesis in dark reactions. Light reactions also generate a proton motive force across the thylakoid membrane, and the proton gradient is used to synthesize ATP. There are two chemical reactions involved in the light reactions: water oxidation in photosystem II, and NADP reduction in photosystem I. The aggregation, arrangement and bonding together of a set of components to form a protein complex, occurring at the level of an individual cell.
