Metalloproteins & Metal Homeostasis

Lucia Banci

Observed metalloprotein maturation inside living cells

The contribution

What this work established

Banci and colleagues developed in-cell NMR approaches that resolve protein chemistry within living human cells. In work on superoxide dismutase 1, they followed zinc binding, protein assembly, and copper uptake at atomic resolution. This made metal-dependent maturation observable in the cellular setting where the protein actually functions.

Why this matters to microbial metallomics

Her contribution helps close a central measurement gap: detecting an element and detecting a protein do not prove that the protein contains the right metal or has matured correctly. The methods offer microbial metallomics and host metal biology a way to test functional metalation rather than infer it.

The next scientific question

The frontier is extending such measurements to more proteins and physiologically relevant conditions, so altered metalation can be distinguished from changes in protein abundance or total metal.

Research background

Uses structural biology and NMR to study metal ions, protein maturation and intracellular metal trafficking. Her group developed in-cell NMR approaches that allow proteins to be examined in living cells at atomic resolution.
