Redox control of copper homeostasis in cyanobacteria
(Taylor & Francis, 2012)
Copper is essential for all living organisms but is toxic when present in excess. Therefore organisms have developed homeostatic mechanism to tightly regulate its cellular concentration. In a recent study we have shown ...

The sRNA NsiR4 is involved in nitrogen assimilation control in cyanobacteria by targeting glutamine synthetase inactivating factor IF7
(National Academy of Sciences, 2015)
Glutamine synthetase (GS), a key enzyme in biological nitrogen assimilation, is regulated in multiple ways in response to varying nitrogen sources and levels. Here we show a small regulatory RNA, NsiR4 (nitrogen stress-induced ...

Redox regulation of glycogen biosynthesis in the cyanobacterium synechocystis sp. PCC 6803: Analysis of the AGP and glycogen synthases
(Oxford University Press, 2014)
Glycogen constitutes the major carbon storage source in cyanobacteria, as starch in algae and higher plants. Glycogen and starch synthesis is linked to active photosynthesis and both of them are degraded to glucose in the ...

Effect of crowding on the electron transfer process from plastocyanin and cytochrome c6 to photosystem I: a comparative study from cyanobacteria to green algae
(Springer Verlag, 2011)
Plastocyanin and cytochrome c 6, the alternate donor proteins to photosystem I, can be acidic, neutral or basic; the role of electrostatics in their interaction with photosystem I vary accordingly for cyanobacteria, algae ...

Redox interference in nitrogen status via oxidative stress is mediated by 2-oxoglutarate in cyanobacteria
(Wiley-Blackwell, 2019)
Reactive oxygen species (ROS) are generated naturally in photosynthetic organisms by respiration and photosynthesis. Therefore, detoxification of these compounds, avoiding oxidative stress, is essential for proper cell ...
