Imaging of intracellular metal partitioning in marine diatoms exposed to metal pollution: consequences to cellular toxicity and metal fate in the environment

Metals induced changes in cell morphology. Metal partitioning showed Cu susceptibility and biomagnification potential, and Ni and Zn detoxification. Frustule accumulation implies Fe and Zn sedimentation.

Identification of major zinc-binding proteins from a marine cyanobacterium: insight into metal uptake in oligotrophic environments

The open ocean cyanobacterium Synechococcus sp. WH8102 thrives at extremely low zinc concentrations. Metalloproteomics experiments have identified an outer-membrane bound porin with zinc-binding ability that is upregulated at low zinc levels, suggesting a role for porins in highly efficient zinc uptake.

About this collection

This collection of papers brings together recent activities in marine biochemistry. This list was initially composed of articles published in a themed issue of Metallomics (6, 2014, guest edited by Rachel Austin) that highlighted emerging high-impact areas of research on metals in marine biochemistry.  Since then, this collection has expanded and will continue to grow to include additional reports in this field, covering various aspects of this important area of metal biology. New articles will be added to this collection as they are published.
