Iron is essential for all life, but it is particularly important to photoautotrophs because of the
many iron-dependent electron transport components in photosynthetic membranes. Since …

Cyanobacteria, red algae, and cryptophytes produce two classes of proteins for light-
harvesting: water-soluble phycobiliproteins and membrane-intrinsic proteins that bind …

Photosynthetic organisms transport and convert solar energy with near-unity quantum
efficiency using large protein supercomplexes held in flexible membranes. The individual …

Oxygenic photosynthesis is driven by photosystems I and II (PSI and PSII, respectively). Both
have specific antenna complexes and the phycobilisome (PBS) is the major antenna protein …

Chlorophyll-based phototrophs, or chlorophototrophs, convert light energy into stored
chemical potential energy using two types of photochemical reaction center (RC), denoted …

Cyanobacterial thylakoid membranes represent the active sites for both photosynthetic and
respiratory electron transport. We used high-resolution atomic force microscopy to visualize …

Under iron-deficiency stress, which occurs frequently in natural aquatic environments,
cyanobacteria reduce the amount of iron-enriched proteins, including photosystem I (PSI) …

Photochemical conversion in oxygenic photosynthesis takes place in two large protein–
pigment complexes named photosystem II and photosystem I (PSII and PSI, respectively) …

The acclimation of cyanobacteria to iron deficiency is crucial for their survival in natural
environments. In response to iron deficiency, many cyanobacterial species induce the …

Iron is an essential component in many protein complexes involved in photosynthesis, but
environmental iron availability is often low as oxidized forms of iron are insoluble in water …
