MetabolomicsMetabolic Response of a Chemolithoautotrophic Archaeon to Carbon Limitation

The ubiquitously distributed ammonia-oxidizing archaea generate energy from ammonia and build cell mass from inorganic carbon sources, thereby contributing to both the global nitrogen and carbon cycles. However, little is known about the regulation of their predicted core carbon metabolism. A the...

MetabolomicsProteome allocations change linearly with the specific growth rate of Saccharomyces cerevisiae under glucose limitation

Saccharomyces cerevisiae is a widely used cell factory; therefore, it is important to understand how it organizes key functional parts when cultured under different conditions. Here, we perform a multiomics analysis of S. cerevisiae by culturing the strain with a wide range of s...

MetabolomicsInorganic Carbon Limitation in Cells of the Wild Type and Photorespiratory Mutants of the Cyanobacterium Synechocystis sp. Strain PCC 6803
The amount of inorganic carbon represents one of the main environmental factors determining productivity of photoautotrophic organisms. Using the model cyanobacterium Synechocystis sp. PCC 6803, we performed a first metabolome study with cyanobacterial cells shifted from high CO2 (5% in air) into co...

MetabolomicsPathogenic NLRP3 mutants form constitutively active inflammasomes resulting in immune-metabolic limitation of IL-1β production

BACKGROUND: Cryopyrin-Associated Periodic Syndrome (CAPS) is an autoinflammatory condition consequence of monoallelic variants in the NLRP3 gene that exacerbate IL-1β production. These variants are gain-of-function, but the exact regulatory mechanism of the NLRP3 CAPS-inflammasom...

TranscriptomicsTranscription Response by sulfur chemolithoautotroph Thiomicrospira crunogenato dissolved inorganic carbon and ammonia limitation
The hydrothermal vent gammaproteobacterium Thiomicrospira crunogena inhabits an unstable environment and must endure dramatic sweeps in habitat chemistry. This sulfur chemolithoautotroph responds to changes in dissolved inorganic carbon (DIC; = CO2 + HCO3- + CO3-2) availability with a carbon concent...

TranscriptomicsTranscription profiling of S. cerevisiae response to nitrogen limitation in chemostat culture
Zinc is indispensable for the catalytic activity and structural stability of many proteins, and its deficiency can have severe consequences for microbial growth in natural and industrial environments. For example, Zn depletion in wort negatively affects beer fermentation and quality. Several studies...

TranscriptomicsTranscription profiling by array of adenylylation of mycobacterial Glnk (PII) protein induced by nitrogen limitation
PII proteins are pivotal regulators of nitrogen metabolism in most prokaryotes, controlling the activities of many targets, including nitrogen assimilation enzymes, two component regulatory systems and ammonium transport proteins. Escherichia coli contains two PII-like proteins, PII (product of glnB...

TranscriptomicsInfluence of oxygen limitation, absence of the cytochrome bc1 complex and low pH on global gene expression in Gluconobacter oxydans 621H using DNA microarray technology
The genome-wide transcriptional responses of the strictly aerobic -proteobacterium Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 complex, and to low pH were studied using DNA microarray analyses. Oxygen limitation caused expression changes of 486 genes, repres...
