2018 journal article

Extremely Thermoacidophilic Metallosphaera Species Mediate Mobilization and Oxidation of Vanadium and Molybdenum Oxides

APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 85(5).

By: G. Wheaton n, N. Vitko n, J. Counts n, J. Dulkis n, I. Podolsky n, A. Mukherjee n, R. Kelly n 

author keywords: Metallosphaera; biomining; extreme thermoacidophily; metal biooxidation; molybdenum; vanadium
MeSH headings : Archaeal Proteins / genetics; Copper / metabolism; Ferric Compounds / metabolism; Gene Expression Profiling; Genome, Archaeal; Hot Temperature; Hydrogen-Ion Concentration; Molybdenum / metabolism; Oxidation-Reduction; Oxides / metabolism; Oxygen; Sulfolobaceae / genetics; Sulfolobaceae / metabolism; Sulfur Compounds / metabolism; Transcriptome; Uranium / metabolism; Vanadium / metabolism
TL;DR: Results suggest that direct oxidation of V and Mo occurs, in addition to Fe-mediated oxidation, such that both direct and indirect mechanisms are involved in the mobilization of redox-active metals by Metallosphaera species. (via Semantic Scholar)

2017 journal article

VapC toxins drive cellular dormancy under uranium stress for the extreme thermoacidophile Metallosphaera prunae

ENVIRONMENTAL MICROBIOLOGY, 19(7), 2831–2842.

By: A. Mukherjee n, G. Wheaton n, J. Counts n, B. Ijeomah n, J. Desai n & R. Kelly n 

MeSH headings : Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Bacterial Toxins / genetics; Bacterial Toxins / metabolism; Gene Expression Regulation, Bacterial / physiology; RNA Stability / physiology; Sulfolobaceae / genetics; Sulfolobaceae / growth & development; Sulfolobaceae / metabolism; Transcriptome; Uranium / metabolism
TL;DR: M. prunae utilizes VapC toxins for post-transcriptional regulation under uranium stress to enter a cellular dormant state, thereby providing an adaptive response to what would otherwise be a deleterious environmental perturbation. (via Semantic Scholar)

By: A. Mukherjee n, G. Wheaton n, P. Blum * & R. Kelly n 

author keywords: uranium oxidation; uranium resistance; chemolithotrophy; terminal oxidases
MeSH headings : Adaptation, Physiological / drug effects; Adaptation, Physiological / genetics; Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Electrophoresis, Gel, Two-Dimensional; Environmental Pollutants / chemistry; Environmental Pollutants / toxicity; Gene Expression Regulation, Archaeal / drug effects; Mutation; RNA Stability / drug effects; RNA, Archaeal / genetics; RNA, Archaeal / metabolism; Species Specificity; Sulfolobaceae / classification; Sulfolobaceae / genetics; Sulfolobaceae / metabolism; Time Factors; Transcriptome / genetics; Uranium / chemistry; Uranium / toxicity
TL;DR: The results point to uranium extremophily as an adaptive, rather than intrinsic, feature for Metallosphaera species, driven by environmental factors. (via Semantic Scholar)
