Changing paradigms for the micronutrient zinc, a known protein cofactor, as a signal relaying also cellular redox state [PDF]
The micronutrient zinc (Zn) is often poorly available but toxic when present in excess, so a tightly controlled Zn homoeostasis network operates in all organisms. This review summarizes our present understanding of plant Zn homoeostasis.

Structure and Catalytic Mechanism of Radical SAM Methylases
Methyl transfer is essential in myriad biological pathways found across all domains of life. Unlike conventional methyltransferases that catalyze this reaction through nucleophilic substitution, many members of the radical S-adenosyl-L-methionine (SAM ...

Oxygen-Sensitive Metalloprotein Structure Determination by Cryo-Electron Microscopy
Metalloproteins are involved in key cell processes such as photosynthesis, respiration, and oxygen transport. However, the presence of transition metals (notably iron as a component of [Fe-S] clusters) often makes these proteins sensitive to oxygen ...
