The light absorption processes associated with photosynthesistake place in large protein complexes known as photosystems. The one known as Photosystem I contains a chlorophylldimer with an absorption peak at 700 nm known as P700. Photosystems are functional and structural units of protein complexes involved in photosynthesis that together carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons. The photosynthetic unit includes the reaction centers (RC 1 and RC 2) and the light-harvesting complexes which contribute to evolution of one O 2 molecule. The light-harvesting complexes, that greatly expand the absorptance capacity of the reactions, have evolved along three principal lines.

2020-06-01 · The photosynthetic apparatus of red algae is unique due to its special light-harvesting antenna, which contains both soluble phycobilisomes, similar to those found in prokaryotic cyanobacteria, and transmembrane light harvesting complex (LHC) proteins, such as LHCR (LHC of red algae) and RedCAPs (red lineage chlorophyll a/b-binding-like proteins) [, , ]. 2020-02-01 · Our MS analysis successfully identified major protein complexes and regulatory proteins of plant photosynthesis electron transport. The major complexes identified include PS II, PS I, cyt b 6 f , ATPase, and NDH, as well as the apoproteins of LHC I and LHC II. With its extensive use of color, it surveys the most important proteins involved in photosynthesis, discussing the structural information we have at our disposal. Most chapters are dedicated to one protein, while a few also summarize general associated concepts.

Photosynthesis occurs in chloroplasts that contain photosystems II and I, the cytochrome bf complex, the Calvin cycle enzymes and pigment-protein complexes containing chlorophyll a, and other antenna pigments (e.g., chlorophyll b in green algae, chlorophyll c and fucaxanthol in brown algae and diatoms, and phycobilins in red algae).

The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. The antenna pigments are predominantly chlorophyll b, xanthophylls, and carotenes. 2011-09-20 · In photosynthetic bacteria, these two steps are carried out in the large membrane protein assembly called the photosynthetic core complex. There are two main constituent proteins in the core complex: light-harvesting complex I (LH1) and the reaction center (RC). Photosynthesis - Photosynthesis - Proteins: Many of the lamellar proteins are components of the chlorophyll–protein complexes described above. Other proteins include enzymes and protein-containing coenzymes.
