ProteomicsBeyond Repression: ArsR Functions as a Global Activator of Metabolic and Redox Responses in Escherichia Coli
The arsenic-responsive repressor, ArsR, has long been understood as a canonical regulator of the arsRBC operon, which confers resistance to arsenic stress. However, recent studies suggest a broader regulatory scope for ArsR. Here, we investigated the proteomic landscape of Escherichia coli strains w...

TranscriptomicsGenomic responses to arsenic in Synechocystis
Arsenic is an ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [AsIII] and arsenate [AsV]. Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by the arsBHC operon and two additional arsenate reductases encoded by the arsI1 and ars...
