Cyanobacteria and red-algae share a common light-harvesting complex which is different
than all other complexes that serve as photosynthetic antennas–the Phycobilisome (PBS) …

In photosynthetic organisms, the production of dangerous oxygen species is stimulated
under high irradiance. To cope with this stress, these organisms have evolved …

Under high irradiance, light becomes dangerous for photosynthetic organisms and they
must protect themselves. Cyanobacteria have developed a simple mechanism, involving a …

Cyanobacteria and green algae harness solar energy to split water and to fix CO 2. Under
specific conditions, they are capable of photoproduction of molecular hydrogen (H 2). This …

Clues to the evolutionary steps producing innovations in oxygenic photosynthesis may be
preserved in the genomes of organisms phylogenetically placed between non …

Carotenoids are lipophilic substances with many biological functions, from coloration to
photoprotection. Being potent antioxidants, carotenoids have multiple biomedical …

Photosynthetic light-harvesting antennae are pigment-binding proteins that perform one of
the most fundamental tasks on Earth, capturing light and transferring energy that enables life …

Orange carotenoid protein (OCP) is a carotenoid-binding protein involved in photo-
protection mechanisms of cyanobacteria. Upon exposure to high light, OCP interconverts …

The orange carotenoid protein (OCP) is a structurally and functionally modular photoactive
protein involved in cyanobacterial photoprotection. Using phylogenomic analysis, we have …
