The latest issue of Metallomics has just gone online, so why not take a look?
On the front cover, Giovanni La Penna (National Research Council Institute, Chemistry of Organometallic Compounds, Italy) and colleagues use X-ray absorption spectroscopy experimental data with detailed first-principle molecular dynamics simulations to look at configurations of zinc ions complexed with β-amyloid (Aβ) peptide.
It is known that Aβ is the main proteinaceous component of the amyloid brain deposits seen in patients suffering from Alzheimer’s disease, and that an increased concentration of transition metals is also found in these plaques. Greater understanding of the relationship between Aβ and these metals is, therefore, of considerable interest.
Zn induced structural aggregation patterns of β-amyloid peptides by first-principle simulations and XAS measurements

On the inside front cover, Xiaolong Xu and colleagues from the University of Science and Technology of China look at the role of Cu2+ in the stabilisation of NAD-glycohydrolase (AA-NADase) from the venom of the pit viper Agkistrodon acutus. It is also known as the ‘hundred-pace snake’, which refers to a local belief that, after being bitten, the victim will only be able to walk 100 steps before dying. AA-NADase from Agkistrodon acutus venom is a unique multicatalytic enzyme with both NADase and AT(D)Pase-like activities.

Both these papers will be free to access for 6 weeks.
