Better force fields start with better data -- A data set of cation dipeptide interactions

  title={Better force fields start with better data -- A data set of cation dipeptide interactions},
  author={Xiaojuan Hu and Maja-Olivia Lenz-Himmer and Carsten Baldauf},
We present a data set from a first-principles study of amino-methylated and acetylated (capped) dipeptides of the 20 proteinogenic amino acids - including alternative possible side chain protonation states and their interactions with selected divalent cations (Ca$^{2+}$, Mg$^{2+}$ and Ba$^{2+}$). The data covers 21,909 stationary points on the respective potential-energy surfaces in a wide relative energy range of up to 4 eV (390 kJ/mol). Relevant properties of interest, like partial charges… Expand

First-principles data set of 45,892 isolated and cation-coordinated conformers of 20 proteinogenic amino acids
The curated data can be utilized for a wide comparison across chemical space of the building blocks of life, for the parametrization of protein force fields, and for the calculation of reference spectra for biophysical applications. Expand
Machine Learning of Partial Charges Derived from High-Quality Quantum-Mechanical Calculations
A machine learning (ML) based approach for predicting partial charges extracted from density functional theory (DFT) electron densities and the training set was chosen with the goal to provide a broad coverage of the known chemical space of druglike molecules. Expand
Relative energetics of acetyl-histidine protomers with and without Zn2+ and a benchmark of energy methods
All tested force fields and semi-empirical methods show a poor performance in reproducing the energy hierarchies of conformers, in particular of systems involving the zinc cation. Expand
Benchmarking polarizable and non-polarizable force fields for Ca2+-peptides against a comprehensive QM dataset.
This work shows how QM-driven parameter development, followed by testing in condensed-phase simulations, may yield FFs that can accurately capture the structure and dynamics of ion-protein interactions. Expand
How cations change peptide structure.
Light is shed on the nature of the underlying interactions, especially regarding effects on the polyamide backbone structure, by comparing the conformational ensembles of model peptides in isolation and in the presence of either Li(+) or Na(+) by using state-of-the-art density-functional theory and gas-phase infrared spectroscopy.

Fast and accurate generation of ab initio quality atomic charges using nonparametric statistical regression
A class of partial atomic charge assignment method that provides ab initio quality description of the electrostatics of bioorganic molecules is introduced that automatically provides an estimate of potential errors in the charge assignment, enabling systematic improvement of these models using additional data.

Trends for isolated amino acids and dipeptides: Conformation, divalent ion binding, and remarkable similarity of binding to calcium and lead
It is shown that only very few distinct backbone structures of isolated amino acids and their dipeptides emerge as lowest-energy conformers, validates past indications that ion-mimicry of calcium and lead should play an important role in a toxicological context. Expand
How well does a restrained electrostatic potential (RESP) model perform in calculating conformational energies of organic and biological molecules?
It can be concluded that a simple “generic” force field with a limited number of specific torsional parameters can describe intraand intermolecular interactions, although all comparison molecules were selected from the authors' 82-compound training set. Expand
Conformational analysis of arginine in gas phase—A strategy for scanning the potential energy surface effectively
It is shown that electronic energies calculated on a DFT level of theory with standard exchange‐correlation functionals strongly underestimate the intramolecular stabilization resulting from stacked orientations of the guanidine and carbonyl moiety of arginine due to the deficiency of DFT to describe dispersion effects.

The present effort shows the possibility of using machine learning techniques to develop descriptive polarizable force field parameters using only QM data and the best model appears to perform even better than the original AMOEBA force field (amoeba09.prm), which was optimized empirically to match liquid properties.
