The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution
Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.

Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Functional divergence of LhcSR and PsbS in zeaxanthin‐mediated non‐photochemical quenching
Summary To protect photosystem II from excess light, non‐photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light‐regulated xanthophyll cycle, which interconverts violaxanthin and zeaxanthin through the opposite activities of violaxanthin de‐epoxidase and ...

ABSTRACT Ethylene plays a crucial role in fruit ripening and is perceived by specialised receptor proteins embedded in the endoplasmic reticulum (ER) membrane. As an ethylene antagonist, 1‐methylcyclopropene (1‐MCP) binds to these receptors and delays papaya ripening, but improper use can cause ripening disorders.
