Inactivation of a heterocyst-specific invertase indicates a principal role of sucrose catabolism in heterocysts of Anabaena sp.
(American Society for Microbiology, 2010)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that carries out N2 fixation in specialized cells called heterocysts, which exchange nutrients and regulators with the filament's vegetative cells that perform ...

Cytochrome c550 in the cyanobacterium Thermosynechococcus elongatus: Study of redox mutants
(American Society for Biochemistry and Molecular Biology Inc., 2004)
Cytochrome c550 is one of the extrinsic Photosystem II subunits in cyanobacteria and red algae. To study the possible role of the heme of the cytochrome c550 we constructed two mutants of Thermosynechococcus elongatus in ...

The cyanobacterial ribosomal-associated protein LrtA is involved in post-stress survival in synechocystis sp. PCC 6803
(Public Library of Science, 2016)
A light-repressed transcript encodes the LrtA protein in cyanobacteria. We show that halflife of lrtA transcript from Synechocystis sp. PCC 6803 is higher in dark-treated cells as compared to light-grown cells, suggesting ...

Sulfide as a signaling molecule in autophagy
(Taylor & Francis, 2013)
Hydrogen sulfide is already recognized as an important signaling molecule in mammalian systems, and emerging data suggest that H2S is a signaling molecule just as important as nitric oxide (NO) and H2O2 in plants. Although ...

NTRC links built-in thioredoxin to light and sucrose in regulating starch synthesis in chloroplasts and amyloplasts
(2009)
Plants have an unusual plastid-localized NADP-thioredoxin reductase C (NTRC) containing both an NADP-thioredoxin reductase (NTR) and a thioredoxin (Trx) domain in a single polypeptide. Although NTRC is known to supply ...

Cytochrome c lysine acetylation regulates cellular respiration and cell death in ischemic skeletal muscle
(Springer Nature, 2023)
Skeletal muscle is more resilient to ischemia-reperfusion injury than other organs. Tissue specific post-translational modifications of cytochrome c (Cytc) are involved in ischemia-reperfusion injury by regulating mitochondrial ...

The Distinctive Regulation of Cyanobacterial Glutamine Synthetase
(MDPI AG, 2018-10-27)
Glutamine synthetase (GS) features prominently in bacterial nitrogen assimilation as it catalyzes the entry of bioavailable nitrogen in form of ammonium into cellular metabolism. The classic example, the comprehensively ...

La coevolución como un sistema de defensa en la interacción planta-patógeno
(Universidad de Málaga, 2016)
Las plantas proveen a diversos tipos de microorganismos de agua y nutrientes. A lo largo del tiempo, plantas y microorganismos han coevolucionado, de forma que los patógenos son capaces de resistir los mecanismos defensivos ...

Cytochrome cM is probably a membrane protein similar to the C subunit of the bacterial nitric oxide reductase
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Cytochrome cM was first described in 1994 and its sequence has been found in the genome of manifold cyanobacterial species ever since. Numerous studies have been carried out with the purpose of determining its function, ...
