1D axial heterostructure of hydrogen-bonded framework and metal-organic framework by metalation reaction [PDF]

Nature Communications
Creating one-dimensional (1D) axial heterostructures of crystals formed from hydrogen-bonded organic frameworks (HOFs) and metal-organic frameworks (MOFs) is challenging due to their distinct chemical bonds to construct each porous architecture.

A flow equilibrium model controlling cytoplasmic transition metal cation pools and preventing mis-metalation as exemplified for zinc homeostasis [PDF]

Journal of Bacteriology
The metal cations of the first transition period fill up their 3d orbitals from 3d5 for Mn(II) to 3d10 for Zn(II). Enzymes use these cations as cofactors and exploit their individual chemical features for important catalytic reactions. A prerequisite for

A metal-trap tests and refines blueprints to engineer cellular protein metalation with different elements [PDF]

Nature Communications
It has been challenging to test how proteins acquire specific metals in cells. The speciation of metalation is thought to depend on the preferences of proteins for different metals competing at intracellular metal-availabilities.
