Truncated recombinant light harvesting complex II proteins are substrates for a protein kinase associated with photosystem II core complexes [PDF]
FEBS Letters, 1998 Previous studies directed towards understanding phosphorylation of the chlorophyll a/b binding proteins comprising light harvesting complex II (LHC II) have concentrated on a single phosphorylation site located close to the N‐terminus of the mature proteins.

Light-induced degradation of D2 protein in isolated photosystem II reaction center complex [PDF]
FEBS Letters, 1992 When isolated photosystem II reaction centers from spinach are exposed to photoinhibitory light in the presence of an electron acceptor, breakdown products of the D2 protein at 28, 25, 23, 18, 9, 5 and 4.5 kDa are detected by immunoblotting with a monospecific anti‐D2 polyclonal antibody.

A novel chlorophyll protein complex in the repair cycle of photosystem II [PDF]
Proceedings of the National Academy of Sciences, 2019 In oxygenic photosynthetic organisms, photosystem II (PSII) is a unique membrane protein complex that catalyzes light-driven oxidation of water. PSII undergoes frequent damage due to its demanding photochemistry. It must undergo a repair and reassembly process following photodamage, many facets of which remain unknown.

Dynamics of photosystem II: a proteomic approach to thylakoid protein complexes [PDF]
Journal of Experimental Botany, 2004 Oxygenic photosynthesis produces various radicals and active oxygen species with harmful effects on photosystem II (PSII). Such photodamage occurs at all light intensities. Damaged PSII centres, however, do not usually accumulate in the thylakoid membrane due to a rapid and efficient repair mechanism.

Evidence for a chlorophylla/b—protein complex associated with Photosystem II [PDF]
FEBS Letters, 1984 A new chlorophylla/b—protein complex designated as LHCPx was separated by SDS—PAGE. This complex differs from the light‐harvesting chla/b—protein of PS II, by its chla/bratio, its fluorescence properties and its apoprotein composition. Evidence is provided that this complex corresponds to a part of PS I antenna.

Assembly of D1/D2 complexes of photosystem II: Binding of pigments and a network of auxiliary proteins [PDF]
Plant Physiology, 2022 Abstract Photosystem II (PSII) is the multi-subunit light-driven oxidoreductase that drives photosynthetic electron transport using electrons extracted from water. To investigate the initial steps of PSII assembly, we used strains of the cyanobacterium Synechocystis sp.

Synthesis and assembly of thylakoid protein complexes: multiple assembly steps of photosystem II [PDF]
Biochemical Journal, 2005 To study the synthesis and assembly of multisubunit thylakoid protein complexes, we performed [35S]Met pulse and chase experiments with isolated chloroplasts and intact leaves of spinach (Spinacia oleracea L.), followed by Blue Native gel separation of the (sub)complexes and subsequent identification of the newly synthesized and assembled protein ...

The PsbQ protein defines cyanobacterial Photosystem II complexes with highest activity and stability [PDF]
Proceedings of the National Academy of Sciences, 2007 Light-induced conversion of water to molecular oxygen by Photosystem II (PSII) is one of the most important enzymatic reactions in the biosphere. PSII is a multisubunit membrane protein complex with numerous associated cofactors, but it continually undergoes assembly and disassembly due to frequent light-mediated damage as a result of its ...

Chlorophyll-Protein Complexes of a Photosystem II Mutant of Maize [PDF]
Plant Physiology, 1984 Use of the octyl beta-d-glucopyranoside solubilization procedure of Camm and Green (1980 Plant Physiol 66: 428-432) reveals that thylakoid membranes of a photosystem (PS) II-deficient maize (Zea mays L.) mutant lack two chlorophyll protein (CP) complexes associated with PSII, i.e. CPa-1 and CPa-2.

Light‐induced D1‐protein degradation in isolated photosystem II core complexes
FEBS Letters, 1990 Photoinhibitory illumination of isolated oxygen evolving photosystem II core complexes results in a substantial degradation of the Dl‐protein which is accompanied by the appearance of high amounts of at least 4 different degradation products. It is suggested that the degradation is due to a protease that is an integral part of the photosystem II ...
