What’s HOT in Issue 10?

Nickel uptake in Escherichia coli

HOT article: Chivers et al., Metallomics, 2012, 4, 1043-1050

Take a look at these HOT articles, which feature in the latest issue of Metallomics.

In their Critical Review, Joseph Cotruvo Jr. and JoAnne Stubbe of MIT, Cambridge, USA, summarise the diversity of ways in which iron and manganese are substituted in similar or identical protein frameworks*

Peter Chivers and colleagues at Washington University School of Medicine, St. Louis, USA, identify the first nickel complex, Ni-(L-His)2, that is imported by microbes. The authors say this should allow more focused studies of the molecular recognition of nickel ions in the environment by organisms that require them for growth.

Michael Linscheid of Humboldt University Berlin, Germany, and collaborators present a methodology to measure the complex adduct spectrum caused by the interaction of Cisplatin with in vivo DNA. The complementary use of molecular and elemental mass spectrometry, say the authors, provides new options to characterize and understand the biological consequences of the wide variety of detected Cisplatin–DNA adducts.

Metallomics Editorial Board Chair, Dr Wolfgang Maret

Also in this issue, an Editorial from the new Chair of our Editorial Board, Dr Wolfgang Maret of King’s College London, and Editor, Dr May Copsey. They look at the history of the field of metallomics, future opportunities for development and how the journal aims to support all researchers investigating the role of metals in the biological sciences.
