Control of metal homeostasis is essential for life in all kingdoms. In most prokaryotic
organisms the FUR (ferric uptake regulator) family of transcriptional regulators is involved in …

Tetrapyrroles are involved in light harvesting and light perception, electron-transfer
reactions, and as co-factors for key enzymes and sensory proteins. Under conditions in …

Approximately 40% of global photosynthesis is conducted by phytoplankton in aquatic
environments. Cyanobacteria, Gram-negative photoautotrophic prokaryotes, contribute …

Iron is an essential nutrient for most living organisms. Due to the low solubility of ferric iron at
physiological pH, the transition from an anaerobic atmosphere to the actual oxidant …

In the nitrogen-fixing heterocyst-forming cyanobacterium Anabaena sp. PCC 7120, the ferric
uptake regulator FurA plays a global regulatory role. Failures to eliminate wild-type copies of …

Cyanobacteria use a series of adaptation strategies and a complicated regulatory network to
maintain intracellular iron (Fe) homeostasis. Here, a global activator named IutR has been …

Heterosigma akashiwo is a harmful algal bloom species that causes significant detrimental
effects on marine ecosystems worldwide. The algicidal bacterium Pseudalteromonas sp. LD …

Knowledge on the regulatory mechanisms controlling iron homeostasis in cyanobacteria is
