• There is a growing need to understand macromolecular behavior within the native cellular environment.
• Cellular Structural Biology aims to bridge this gap.

Purpose of the Study:

• To review and discuss the contributions of in-cell Nuclear Magnetic Resonance (NMR) to Cellular Structural Biology.
• To highlight the importance of studying macromolecules within their native cellular context.
• To showcase how in-cell NMR elucidates protein structure, dynamics, and function in living cells.

Main Methods:

• In-cell Nuclear Magnetic Resonance (NMR) spectroscopy.
• Application of NMR to investigate macromolecules directly within living cells.
• Analysis of structural and dynamical properties of proteins in a cellular environment.

Main Results:

• In-cell NMR provides atomic resolution insights into protein structure and dynamics within cells.
• This technique allows for the study of functional processes directly in living cells.
• Factors modulating protein function, such as partner proteins and oxidative stress, can be investigated.

Conclusions:

• In-cell NMR is a powerful tool for Cellular Structural Biology.
• It offers unique advantages for understanding protein behavior and function in a native cellular context.
• This approach significantly enhances the biological relevance of structural characterization.
