Pumping iron makes thinner diatoms

Pumping iron

The primary role of the ZIP13 metal transporter in flies is to move iron ions out of cells, rather than moving zinc ions into cells, as is the case in human cells.

Pumping iron: conserved iron deficiency responses in the plant lineage.

Pumping iron: mechanisms for iron uptake by Campylobacter.

Campylobacter requires iron for successful colonization of the host. In the last 7 years, a wealth of data has been generated allowing detailed molecular characterization of Campylobacter iron-uptake systems. Several exogenous siderophores have been identified as sources of ferric iron for Campylobacter. Ferri-enterochelin uptake requires both the outer-membrane receptor protein CfrA and the in...

Diversity and Evolutionary History of Iron Metabolism Genes in Diatoms

Ferroproteins arose early in Earth's history, prior to the emergence of oxygenic photosynthesis and the subsequent reduction of bioavailable iron. Today, iron availability limits primary productivity in about 30% of the world's oceans. Diatoms, responsible for nearly half of oceanic primary production, have evolved molecular strategies for coping with variable iron concentrations. Our understan...

JCB • VOLUME 168 • NUMBER 3 • 2005 348 Saving varicella from suicide aricella zoster virus (VZV) causes both varicella (chickenpox) and zoster (shingles). VZV spreads throughout the body, but it does so slowly, and virus only emerges extracellularly in the skin where it can spread to other hosts. That behavior is now explained by Zhenglun Zhu (Harvard Medical School, Boston, MA), Jason Chen, An...
