Dynamics of the Intrinsically Disordered Inhibitor IF7 of Glutamine Synthetase in Isolation and in Complex with its Partner
(Elsevier, 2020)
Glutamine synthetase (GS) catalyzes the ATP-dependent formation of glutamine from glutamate and ammonia. The activity of Synechocystis sp. PCC 6803 GS is regulated, among other mechanisms, by protein-protein interactions ...

A core of three amino acids at the carboxyl-terminal region of glutamine synthetase defines its regulation in cyanobacteria
(Wiley, 2015)
Glutamine synthetase (GS) type I is a key enzyme in nitrogen metabolism, and its activity is finely controlled by cellular carbon/nitrogen balance. In cyanobacteria, a reversible process that involves protein-protein ...

CopM is a novel copper-binding protein involved in copper resistance in Synechocystis sp. PCC 6803
(Wiley Open Access, 2015)
Copper resistance system in the cyanobacterium Synechocystis sp. PCC 6803 comprises two operons, copMRS and copBAC, which are expressed in response to copper in the media. copBAC codes for a heavy-metal efflux–resistance ...

Depletion of m-type thioredoxin impairs photosynthesis, carbon fixation, and oxidative stress in cyanobacteria
(Oxford University Press, 2021)
Thioredoxins (Trxs) are disulfide oxidoreductases that regulate many biological processes. The m-type thioredoxin (TrxA) is the only Trx present in all oxygenic photosynthetic organisms. Extensive biochemical and proteomic ...
