ABSTRACT Carbon/nitrogen (C/N) balance sensing is a key requirement for the
maintenance of cellular homeostasis. Therefore, cyanobacteria have evolved a …

Carbon and nitrogen are the two most abundant nutrient elements for all living organisms,
and their metabolism is tightly coupled. What are the signaling mechanisms that cells use to …

Nitrogen limitation imposes a major transition in the lifestyle of nondiazotrophic
cyanobacteria that is controlled by a complex interplay of regulatory factors involving the …

Nitrogen availability is a growth-limiting factor in many habitats, and the global nitrogen
cycle involves prokaryotes and eukaryotes competing for this precious resource. Only some …

Photosynthetic cyanobacteria are important primary producers and model organisms for
studying photosynthesis and elements cycling on earth. Due to the ability to absorb sunlight …

As the key enzyme of bacterial nitrogen assimilation, glutamine synthetase (GS) is tightly
regulated. In cyanobacteria, GS activity is controlled by the interaction with inactivating …

Cyanobacteria evolved sophisticated mechanisms allowing them to cope with
environmental depletion of combined nitrogen. Here, we describe progress in …

PII signal transduction proteins are widely spread among all domains of life where they
regulate a multitude of carbon and nitrogen metabolism related processes. Non-diazotrophic …

The overexpression of the RuBisCO (rbc) gene has recently become an achievable strategy
for increasing cyanobacterial biomass and overcoming the biocompound production …

When the supply of inorganic carbon is limiting, photosynthetic cyanobacteria excrete nitrite,
a toxic intermediate in the ammonia assimilation pathway from nitrate. It has been …
