Bioinformatics of Metalloproteins and Metalloproteomes [PDF]
Trace metals are inorganic elements that are required for all organisms in very low quantities. They serve as cofactors and activators of metalloproteins involved in a variety of key cellular processes.

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.

Machine Learning Approaches for Metalloproteins [PDF]
Metalloproteins are a family of proteins characterized by metal ion binding, whereby the presence of these ions confers key catalytic and ligand-binding properties.

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 ...
