Open Biology, 2021 There is a surprisingly high morphological similarity between multilamellar concentric thylakoids in cyanobacteria and the myelin sheath that wraps the nerve axons. Thylakoids are multilamellar structures, which express photosystems I and II, cytochromes

Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]
, 1980 Subfractions isolated from intact purified spinach chloroplasts are able to prenylate the aromatic moiety of -tocopherol and plastoquinone-9 precursors. The biosynthesis of -tocopherol and plastoquinone-9 is a compartmentalized process.

Biogenesis and origin of thylakoid membranes
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2001 Thylakoids are photosynthetically active membranes found in Cyanobacteria and chloroplasts. It is likely that they originated in photosynthetic bacteria, probably in close connection to the occurrence of photosystem II and oxygenic photosynthesis. In higher plants, chloroplasts develop from undifferentiated proplastids.

Charge regulation radically modifies electrostatics in membrane stacks [PDF]
Phys. Rev. E 100, 050601 (2019), 2019 Motivated by biological membrane-containing organelles in plants and photosynthetic bacteria, we study charge regulation in a model membrane stack. Considering (de)protonation as the simplest mechanism of charge equilibration between the membranes and with the bathing environment, we uncover a symmetry-broken charge state in the stack with a ...

Models and measurements of energy-dependent quenching. [PDF]
, 2013 Energy-dependent quenching (qE) in photosystem II (PSII) is a pH-dependent response that enables plants to regulate light harvesting in response to rapid fluctuations in light intensity.

eLife, 2021 During photosynthesis, electron transport is necessary for carbon assimilation and must be regulated to minimize free radical damage. There is a longstanding controversy over the role of a critical enzyme in this process (ferredoxin:NADP(H ...

Membrane-Specific Targeting of Tail-Anchored Proteins SECE1 and SECE2 Within Chloroplasts.
Frontiers in Plant Science, 2019 Membrane proteins that are imported into chloroplasts must be accurately targeted in order to maintain the identity and function of the highly differentiated internal membranes.

Thylakoid Membrane Bioenergetics
, 2018 Oxygenic photosynthesis is a unique and essential photochemical process in which solar energy is used to oxidize water and to form carbohydrates. In this process molecular oxygen is released as a by-product. Thylakoid membranes are specialized photosynthetic electron transfer membranes which represent one of the most elaborate bioenergetic machines ...

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen [PDF]
, 2012 Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity.
