Heterocyst Thylakoid Bioenergetics [PDF]
Life, 2019 Heterocysts are specialized cells that differentiate in the filaments of heterocystous cyanobacteria. Their role is to maintain a microoxic environment for the nitrogenase enzyme during diazotrophic growth.

Coexistence between fluid and crystalline phases of proteins in photosynthetic membranes [PDF]
, 2013 Photosystem II (PSII) and its associated light-harvesting complex II (LHCII) are highly concentrated in the stacked grana regions of photosynthetic thylakoid membranes. Within the membrane, PSII-LHCII supercomplexes can be arranged in disordered packings, ordered arrays, or mixtures thereof.

Light Adaptation in Phycobilisome antennas: Influence on the Rod Length and Structural Arrangement [PDF]
J. Phys. Chem. B 121, 9196 (2017), 2017 Phycobilisomes, the light-harvesting antennas of cyanobacteria, can adapt to a wide range of environments thanks to a composition and function response to stress conditions. We study how structural changes influence excitation transfer in these super-complexes.

Evolutionary Patterns of Thylakoid Architecture in Cyanobacteria [PDF]
Frontiers in Microbiology, 2019 While photosynthetic processes have become increasingly understood in cyanobacterial model strains, differences in the spatial distribution of thylakoid membranes among various lineages have been largely unexplored.

Light induced changes in protein expression and uniform regulation of transcription in the thylakoid lumen of Arabidopsis thaliana. [PDF]
PLoS ONE, 2009 In plants oxygenic photosynthesis is performed by large protein complexes found in the thylakoid membranes of chloroplasts. The soluble thylakoid lumen space is a narrow and compressed region within the thylakoid membrane which contains 80-200 proteins ...

The journey of preproteins across the chloroplast membrane systems
Frontiers in Physiology, 2023 The photosynthetic capacity of chloroplasts is vital for autotrophic growth in algae and plants. The origin of the chloroplast has been explained by the endosymbiotic theory that proposes the engulfment of a cyanobacterium by an ancestral eukaryotic cell

DNA-assembled nanoarchitectures with multiple components in regulated and coordinated motion [PDF]
Science Advances Vol. 5, no. 11, eaax6023 (2019), 2021 Coordinating functional parts to operate in concert is essential for machinery. In gear trains, meshed gears are compactly interlocked, working together to impose rotation or translation. In photosynthetic systems, a variety of biological entities in the thylakoid membrane interact with each other, converting light energy into chemical energy. However,

A Sec14 domain protein is required for photoautotrophic growth and chloroplast vesicle formation in Arabidopsis thaliana. [PDF]
, 2020 In eukaryotic photosynthetic organisms, the conversion of solar into chemical energy occurs in thylakoid membranes in the chloroplast. How thylakoid membranes are formed and maintained is poorly understood.

A brief history of thylakoid biogenesis [PDF]
Open Biology, 2019 The thylakoid membrane network inside chloroplasts harbours the protein complexes that are necessary for the light-dependent reactions of photosynthesis. Cellular processes for building and altering this membrane network are therefore essential for life on Earth.
