Mapping energy citizenship in the south of Europe.

The adoption of new global approaches in the field of energy democratization requires inquiring into how people act to shape the energy system. This is where the concept of energy citizenship (ENCI) appears as a constellation of actors that enable and/or support citizens to became active participants in the debates and energy systems both in private and public sphere, or as a collective citizen that contributes to change (Pel et al., 2021).

Glutamine synthetase degradation is controlled by oxidative proteolysis in the marine cyanobacterium Prochlorococcus marinus strain PCC 9511.

Prochlorococcus is one of the most important primary producers on Earth; its unusual features and ecological importance have made it a model organism, but nutrient assimilation has received little attention. Glutamine synthetase (GS) plays a key role in nitrogen metabolism and its central position justifies the fine regulation of this enzyme. The aim of this work is to demonstrate the involvement of metal-catalyzed oxidation (MCO) in the control of the biological activity and turnover of GS from Prochlorococcus.
