Metalloproteomics is an emerging scientific field. It is focused to investigate the distributions and compositions of all metalloproteins in a proteome, their structural and functional characterization and their structural metal-binding moieties. Various nuclear analytical techniques, such as...
Microorganisms use a variety of strategies to extract trace metals from minerals. In addition to meeting metabolic needs, these microbe–mineral interactions affect mineral weathering and element cycling. Evidence of these interactions in the geological record could be used as "biosignatures" to...
Cadmium is one of the most widespread metals which is highly toxic, and can enter the human food chain directly via accumulation in nutritional plants. To better understand the transport and protein binding capabilities of heavy metals we have investigated cadmium uptake in Spinacia oleracea L.,...
A methodology using the on-line combination of micro-HPLC with ICP-MS and electrospray ionisation (ESI) MS/MS, GC-ICP-MS and GC-TOFMS is proposed for investigation of the Se species distribution in lysates and headspace of human lymphoma cell lines after incubation with methylseleninic acid...
This work focuses on phytochelatins (PCs) in plants chronically exposed to low or moderate metal concentrations in soil, which commonly occurs in natural environments. The original approach was to evaluate PCs in nopal ( Opuntia ficus ) in relation to the plant and soil levels of Cd, Pb, Cu and...
High-precision isotopic analyses by MC-ICP-MS were used to investigate the mass-dependent fractionation of Mo and Fe isotopes during bacterial metal assimilation in experiments with Azotobacter vinelandii . A. vinelandii is a diazotroph with high demand for both Mo and Fe during nitrogen...
