ProteomicsMorphological plasticity in a sulfur-oxidizing bacterium from the SUP05 clade enhances dark carbon fixation
Sulfur-oxidizing bacteria from the SUP05 clade are abundant in anoxic and oxygenated marine waters that appear to lack reduced sources of sulfur for cell growth. This raises questions about how these chemosynthetic bacteria survive across oxygen and sulfur gradients and how their mode of survival im...

ProteomicsHeterotrophic carbon metabolism and energy acquisition in Candidatus Thioglobus singularis strain PS1, a member of the SUP05 clade of marine Gammaproteobacteria
The balance between autotrophy and heterotrophy regulates the size of the ocean’s carbon sink. The contribution of a particular bacterial or archaeal lineage to carbon flux is determined by its metabolism, which may vary within lineages and may depend on environmental conditions. Members of the SUP...

ProteomicsStress response of a marine ammonia-oxidizing archaeon informs physiological status of environmental populations
High representation by ammonia-oxidizing archaea (AOA) in marine systems is consistent with their high affinity for ammonia, efficient carbon fixation, and copper (Cu)-centric respiratory system. However, little is known about their response to nutrient stress. We therefore used global transcripti...

ProteomicsProchlorococcus extracellular vesicles: molecular composition and adsorption to diverse microbes
Extracellular vesicles are small (50-200 nm diameter) membrane-bound structures released by cells from all domains of life. Vesicles have been implicated in numerous microbial processes, including gene transfer, signaling, pathogenesis, and defense. While vesicles are abundant in the oceans, little ...

ProteomicsTargeted mass spectrometry enables multiplexed quantification of immunomodulatory proteins in clinical biospecimens
Immunotherapies are revolutionizing cancer care, producing durable responses and potentially cures in a subset of patients. However, response rates are low for most tumors, grade 3/4 toxicities are not uncommon, and our current understanding of tumor immunobiology is incomplete. While hundreds of im...
