An organized light-harvesting and reaction-center assembly supporting photosynthetic energy conversion.
Photosystem I is a light-driven reaction-centre complex in oxygenic photosynthesis. Excitation supports electron transfer to acceptors including ferredoxin; the balance between linear and cyclic routes affects reductant and ATP supply.
A photosystem involved in water oxidation during oxygenic photosynthesis. Its reaction-center components include D1 protein.
The manganese–calcium-containing catalytic machinery that extracts electrons from water in oxygenic photosynthesis. Four oxidizing equivalents permit formation of one oxygen molecule from two water molecules.
LHCII is a major light-harvesting antenna complex in plants. A regulated mobile fraction participates in photosynthetic state transitions; antenna redistribution is distinct from simply dissipating excitation.
PsbS participates in rapid proton-dependent regulation of photosynthetic antenna quenching in plants. Loss of PsbS-dependent quenching can be separated experimentally from loss of light-harvesting capacity.
Processes replacing damaged photosystem II components and restoring functional complexes. Regulated D1 protein synthesis is one part of this cycle.
A reaction-center protein of photosystem II, encoded by psbA messenger RNA in chloroplast expression systems. Damage creates demand for replacement during photosystem II repair.
