In turn, drug design process, especially the fragment-based approaches, could benefit from the knowledge. Retrospective virtual screening campaigns by employing AutoDock Vina followed by protein-ligand interaction finger- printing (PLIF) identification by using recently published PyPLIF HIPPOS were the main techniques used here. The ligands and decoys datasets from the enhanced version of the database of useful de- coys (DUDE) targeting human G protein-coupled receptors (GPCRs) were employed in this research since the mutation data are available and could be used to retrospectively verify the prediction. The results show that the method presented in this article could pinpoint some retrospectively verified molecular determinants. The method is therefore suggested to be employed as a routine in drug Citation: Istyastono, E.P.; Yuniarti, design and discovery. N.; Prasasty, V.D.; Mungkasi, S.

Secondary Structure Propensities in Peptide Folding Simulations: a Systematic Comparison of Molecular Mechanics Interaction Schemes
Biophysical Journal Volume 97 July 2009 599–608 599 Secondary Structure Propensities in Peptide Folding Simulations: A Systematic Comparison of Molecular Mechanics Interaction Schemes Dirk Matthes and Bert L. de Groot* Department of Theoretical and Computational Biophysics, Computational Biomolecular Dynamics Group, Max-Planck-Institute for Biophysical Chemistry, Go¨ttingen, Germany ABSTRACT We present a systematic study directed toward the secondary structure propensity and sampling behavior in peptide folding simulations with eight different molecular dynamics force-field variants in explicit solvent. We report on the combi- national result of force field, water model, and electrostatic interaction schemes and compare to available experimental charac- terization of five studied model peptides in terms of reproduced structure and dynamics. The total simulation time exceeded 18 ms and included simulations that started from both folded and extended conformations. Despite remaining sampling issues, a number of distinct trends in the folding behavior of the peptides emerged. Pronounced differences in the propensity of finding prominent secondary structure motifs in the different applied force fields suggest that problems point in particular to the balance of the relative stabilities of helical and extended conformations. INTRODUCTION Molecular dynamics (MD) simulations are routinely utilized to that study, simulations of relatively short lengths were per- study the folding dynamics of peptides and small proteins as formed and the natively folded state was used as starting well as biomolecular aggregation.

ORGANIZATION OF BIOMOLECULES IN A 3-DIMENSIONAL SPACE by Sameer Sajja A thesis submitted to the faculty of The University of North Carolina at Charlotte in partial fulfillment of the requirements for the degree of Master of Science in Chemistry Charlotte 2019 Approved by: ________________________________ Dr. Kirill Afonin ________________________________ Dr. Caryn Striplin ________________________________ Dr. Joanna Krueger ________________________________ Dr. Yuri Nesmelov ii ©2019 Sameer Sajja ALL RIGHTS RESERVED iii ABSTRACT SAMEER SAJJA. Organization of Biomolecules in a 3-Dimensional Space (Under the direction of DR. KIRILL A. AFONIN) The human body operates using various stimuli-responsive mechanisms, dictating biological activity via reaction to external cues. Hydrogels are networked hydrophilic polymeric materials that offer the potential to recreate aqueous environments with controlled organization of biomolecules for research purposes and potential therapeutic use. The unique, programmable structure of hydrogels exhibit similar physicochemical properties to those of living tissues while also introducing component-mediated biocompatibility. The design of stimuli-responsive biocompatible hydrogels would further allow for controllable mechanical and functional properties tuned by changes in environmental factors. This study investigates individual biomolecular components needed to potentially engineer biocompatible and stimuli-responsive hydrogels. By utilizing programmable biomolecules such as nucleic acids (DNA and RNA) and proteins -
