A Comparison of Bonded and Nonbonded Zinc(II) Force Fields with NMR Data. Int J Mol Sci 2023; 24:ijms24065440. [PMID: 36982515 PMCID: PMC10055966 DOI: 10.3390/ijms24065440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 02/16/2023] [Accepted: 02/22/2023] [Indexed: 03/18/2023] Open
Abstract
Classical molecular dynamics (MD) simulations are widely used to inspect the behavior of zinc(II)-proteins at the atomic level, hence the need to properly model the zinc(II) ion and the interaction with its ligands. Different approaches have been developed to represent zinc(II) sites, with the bonded and nonbonded models being the most used. In the present work, we tested the well-known zinc AMBER force field (ZAFF) and a recently developed nonbonded force field (NBFF) to assess how accurately they reproduce the dynamic behavior of zinc(II)-proteins. For this, we selected as benchmark six zinc-fingers. This superfamily is extremely heterogenous in terms of architecture, binding mode, function, and reactivity. From repeated MD simulations, we computed the order parameter (S2) of all backbone N-H bond vectors in each system. These data were superimposed to heteronuclear Overhauser effect measurements taken by NMR spectroscopy. This provides a quantitative estimate of the accuracy of the FFs in reproducing protein dynamics, leveraging the information about the protein backbone mobility contained in the NMR data. The correlation between the MD-computed S2 and the experimental data indicated that both tested FFs reproduce well the dynamic behavior of zinc(II)-proteins, with comparable accuracy. Thus, along with ZAFF, NBFF represents a useful tool to simulate metalloproteins with the advantage of being extensible to diverse systems such as those bearing dinuclear metal sites.

Abstract
![]()
A detailed knowledge
of the complex processes that make cells and
organisms alive is fundamental in order to understand diseases and
to develop novel drugs and therapeutic treatments. To this aim, biological
macromolecules should ideally be characterized at atomic resolution
directly within the cellular environment. Among the existing structural
techniques, solution NMR stands out as the only one able to investigate
at high resolution the structure and dynamic behavior of macromolecules
directly in living cells. With the advent of more sensitive NMR hardware
and new biotechnological tools, modern in-cell NMR approaches have
been established since the early 2000s. At the coming of age of in-cell
NMR, we provide a detailed overview of its developments and applications
in the 20 years that followed its inception. We review the existing
approaches for cell sample preparation and isotopic labeling, the
application of in-cell NMR to important biological questions, and
the development of NMR bioreactor devices, which greatly increase
the lifetime of the cells allowing real-time monitoring of intracellular
metabolites and proteins. Finally, we share our thoughts on the future
perspectives of the in-cell NMR methodology.

Abstract
Nuclear magnetic resonance (NMR) spectroscopy is a well-established method for analyzing protein structure, interaction, and dynamics at atomic resolution and in various sample states including solution state, solid state, and membranous environment. Thanks to rapid NMR methodology development, the past decade has witnessed a growing number of protein NMR studies in complex systems ranging from membrane mimetics to living cells, which pushes the research frontier further toward physiological environments and offers unique insights in elucidating protein functional mechanisms. In particular, in-cell NMR has become a method of choice for bridging the huge gap between structural biology and cell biology. Herein, we review the recent developments and applications of NMR methods for protein analysis in close-to-physiological environments, with special emphasis on in-cell protein structural determination and the analysis of protein dynamics, both difficult to be accessed by traditional methods.
