TranscriptomicsM. sedula transcriptional response to ferrous iron and RISC supplements
Abstract: The crenarchaeal order Sulfolobales collectively contains at least five major terminal oxidase complexes. Based on genome sequence information, all five complexes are found only in Metallosphaera sedula and Sulfolobus tokodaii, the two sequenced Sulfolobales capable of iron oxidization. Wh...

ProteomicsThe influence of iron availability on protein carbonylation in Arabidopsis thaliana plant
The study examined the proteins that were specifically carbonylated in the wild-type seedlings exposed to iron-deficiency conditions. The results indicated that proteins were differentially carbonylated between the wild type and the triple ferritin mutant Fer1-3-4 in the leaves, stem, and flowers in...

Proteomics,MultiomicsTranscriptional and translational regulatory responses to iron limitation in the globally distributed marine bacterium Candidatus Pelagibacter ubique
Investigation of the gene expression responses of Candidatus Pelagibacter ubique cultures to iron limitation in natural seawater media supplemented with a siderophore to chelate iron. Quantitative peptide mass spectrometry revealed that sfuC protein abundance increased 27-fold, despite an average de...

ProteomicsInsights into autotrophic activities and carbon flow in iron-rich pelagic aggregates (iron snow)
Pelagic aggregates function as hotspots for microbial activity and biological carbon pumps for exporting OM fixed by photoautotrophs to sediments in lakes and oceans. In iron-rich (ferruginous) lakes, photoferrotrophic or chemolithoautotrophic bacteria appear to contribute to CO2 fixation by oxidizi...

TranscriptomicsTranscriptional Response of 0.1%YE-grown M. sedula cells to ferrous sulfate
(from abstract): Iron oxidation is a desirable trait of biomining microorganisms, although the mechanism is not well-understood in extreme thermoacidophiles. The complete genome sequence of the extremely thermoacidophilic archaeon Metallosphaera sedula DSM 5348 (2.2 Mb, ~2300 ORFs) provides insights...

ProteomicsMechanisms of microbial magnetite oxidation by Sideroxydans lithotrophicus ES-1
Iron-oxidizing bacteria are widely found in natural and man-made environments where they influence varied biogeochemical cycles. Despite their prevalence, the mechanisms and Fe(II) substrates used by these organisms remain understudied. To date, there has been limited exploration of the ability of i...

TranscriptomicsTranscription profiling of S. cerevisiae (budding yeast) mutants reveals Isc1p plays a key role in hydrogen peroxide resistance and chronological lifespan through modulation of iron levels and programmed cell death
Changes in the transcriptome of Isc1p deficient mutants. The inositolphosphosphingolipid phospholipase C (Isc1p) of Saccharomyces cerevisiae belongs to the family of neutral sphingomyelinases that generates the bioactive sphingolipid ceramide. In this work the role of Isc1p in oxidative stress resis...
