Non-intrusive Assessment of Photosystem II and Photosystem I in Whole Coral Tissues

Frontiers in Marine Science, 2017
Reef building corals (phylum Cnidaria) harbor endosymbiotic dinoflagellate algae (genus Symbiodinium) that generate photosynthetic products to fuel their host's metabolism.

Role of Plastid Protein Phosphatase TAP38 in LHCII Dephosphorylation and Thylakoid Electron Flow [PDF]

, 2010
Short-term changes in illumination elicit alterations in thylakoid protein phosphorylation and reorganization of the photosynthetic machinery. Phosphorylation of LHCII, the light-harvesting complex of photosystem II, facilitates its relocation to ...

One‐Pot Biphasic Photocatalytic CO2‐to‐Carbonylation Cascades

Angewandte Chemie, EarlyView.
Bioinspired biphasic compartmentalization enables one‐pot cascades where photocatalytic CO2 reduction generates CO for carbonylative cross‐couplings to synthesize complex organic products, including a pharmaceutical. ABSTRACT Photosynthesis compartmentalizes reactions across the thylakoid membrane in vivo to upcycle CO2 into complex chemicals that are ...

Cryo-EM and femtosecond spectroscopic studies provide mechanistic insight into the energy transfer in CpcL-phycobilisomes

Nature Communications, 2023
Phycobilisomes (PBS) are the major light harvesting complexes of photosynthesis in the cyanobacteria and red algae. CpcL-PBS is a type of small PBS in cyanobacteria that transfers energy directly to photosystem I without the core structure.

Light‐Driven Out‐of‐Equilibrium Helicity Control in a Diarylethene–Helicene Photosystem

Angewandte Chemie, EarlyView.
Distinct energy landscapes of different helicities in the open and closed states of a diarylethene–helicene photoswitch enable a light‐driven energy ratchet. Helix inversion occurs selectively in the closed form, and the resulting helicity is transferred and kinetically trapped upon ring opening, generating a persistent out‐of‐equilibrium chiral state ...
