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 …

Over the past 15 years, the genetic basis for production of many cyanobacterial bioactive
compounds has been described. This knowledge has enabled investigations into the …

This review summarizes recent aspects of (di) nitrogen fixation and (di) hydrogen
metabolism, with emphasis on cyanobacteria. These organisms possess several types of the …

Microcystins are toxins produced by cyanobacteria that entail serious health and
environmental problems. They are cyclic heptapeptides synthesized via a mixed polyketide …

Marine primary producers adapted over eons to the changing chemistry of the oceans.
Because a number of metalloenzymes are necessary for N assimilation, changes in the …

Cyanobacteria are photosynthesizing microorganisms that can be used as a model for
analyzing gene expression. The expression of genes involves transcription and translation …

Although intensification of toxic cyanobacterial blooms over the last decade is a matter of
growing concern due to bloom impact on water quality, the biological role of most of the …

Nitrogen (N) transformations and fluxes at the sediment‐water interface (SWI) were
measured in Missisquoi Bay, Lake Champlain, to clarify the role of N in cyanobacterial …

2-oxogluatarate (2-OG), a metabolite of the highly conserved Krebs cycle, not only plays a
critical role in metabolism, but also constitutes a signaling molecule in a variety of organisms …

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