Distinct features of C/N balance regulation in Prochlorococcus sp. strain MIT9313
Domínguez-Martín, María A.; López-Lozano, Antonio; Rangel Zúñiga, Oriol Alberto; Díez, Jesús; García-Fernández, José Manuel (Oxford University Press, 2018)The abundance and significant contribution to global primary production of the marine cyanobacterium Prochlorococcus have made it one of the main models in marine ecology. Several conditions known to cause strong effects ... -
Diversity of regulatory mechanisms in the C/N metabolism of the marine cyanobacteria Prochlorococcus and synechococcus
Domínguez-Martín, María A. (Universidad de Córdoba, Servicio de Publicaciones, 2015)Marine picocyanobacteria are the most abundant photosynthetic organisms on Earth, with only two genera, Prochlorococcus (Johnson et al., 2006, Olson et al., 1990, Partensky et al., 1999) and Synechococcus (Scanlan, 2003, ... -
Glutamine Synthetase Sensitivity to Oxidative Modification during Nutrient Starvation in Prochlorococcus marinus PCC 9511
Gómez-Baena, Guadalupe; Domínguez-Martín, María A.; Donaldson, Robert P.; García-Fernández, José Manuel; Díez Dapena, Jesús (Public Library of Science, 2015)Glutamine synthetase plays a key role in nitrogen metabolism, thus the fine regulation of this enzyme in Prochlorococcus, which is especially important in the oligotrophic oceans where this marine cyanobacterium thrives. ... -
Marine Synechococcus sp. Strain WH7803 Shows Specific Adaptative Responses to Assimilate Nanomolar Concentrations of Nitrate
Domínguez-Martín, María A.; López-Lozano, Antonio; Melero-Rubio, Yesica; Gómez-Baena, Guadalupe; Jiménez-Estrada, Juan Andrés; Kukil, Kateryna; Díez, Jesús; García-Fernández, José Manuel (American Society for Microbiology, 2022)Marine Synechococcus, together with Prochlorococcus, contribute to a significant proportion of the primary production on Earth. The spatial distribution of these two groups of marine picocyanobacteria depends on different ... -
Molecular basis for the distinct divalent cation requirement in the uridylylation of the signal transduction proteins GlnJ and GlnB from Rhodospirillum rubrum
Teixeira, Pedro Filipe; Nordlund, Stefan; Domínguez-Martín, María A. (BioMed Central, 2012)Background: PII proteins have a fundamental role in the control of nitrogen metabolism in bacteria, through interactions with different PII targets, controlled by metabolite binding and post-translational modification, ... -
Nitrogen starvation induces extensive changes in the redox proteome of Prochlorococcus sp. strain SS120
McDonagh, B.; Domínguez-Martín, María A.; Gómez-Baena, Guadalupe; López-Lozano, Antonio; Díez, Jesús; Bárcena Ruiz, José Antonio; García-Fernández, José Manuel (Wiley, 2012)Very low nitrogen concentration is a critical limitation in the oligotrophic oceans inhabited by the cyanobacterium Prochlorococccus, one of the main primary producers on Earth. It is well known that nitrogen starvation ... -
Physiological Regulation of Isocitrate Dehydrogenase and the Role of 2-Oxoglutarate in Prochlorococcus sp. Strain PCC 9511
Domínguez-Martín, María A.; López-Lozano, Antonio; Díez Dapena, Jesús; Gómez-Baena, Guadalupe; Rangel Zúñiga, Oriol Alberto; García-Fernández, José Manuel (Public Library of Science, 2014)The enzyme isocitrate dehydrogenase (ICDH; EC 1.1.1.42) catalyzes the oxidative decarboxylation of isocitrate, to produce 2- oxoglutarate. The incompleteness of the tricarboxylic acids cycle in marine cyanobacteria confers ... -
Regulatory and metabolic adaptations in the nitrogen assimilation of marine picocyanobacteria
Díez, Jesús; López-Lozano, Antonio; Domínguez-Martín, María A.; Gómez-Baena, Guadalupe; Muñoz Marín, Mª Carmen; Melero-Rubio, Yesica; García-Fernández, José Manuel (Oxford University Press, 2022)Prochlorococcus and Synechococcus are the two most abundant photosynthetic organisms on Earth, with a strong influence on the biogeochemical carbon and nitrogen cycles. Early reports demonstrated the streamlining of ...
