Summary
We developed a new web platform for discrete molecular dynamics (DMD) simulations, enabling large-scale protein folding and dynamics studies. This tool helps uncover protein properties at relevant scales for mechanistic insights.
Area of Science:
- Computational Biology
- Biophysics
- Structural Biology
Background:
- Simulating protein folding requires exploring vast conformational landscapes.
- Conventional methods struggle with relevant time and length scales for mechanistic understanding.
- Discrete Molecular Dynamics (DMD) can bridge these gaps for studying protein dynamics.
Purpose of the Study:
- To introduce a novel web-based platform, the iFold server, for performing discrete molecular dynamics simulations.
- To enable large-scale simulations of protein folding and related phenomena.
- To provide tools for analyzing protein structural and biological properties.
Main Methods:
- Utilizing discrete molecular dynamics (DMD) simulations.
- Employing a coarse-grained protein model with structure-based Gō-interactions.
- Implementing the iFold web server for accessibility and large-scale analysis.
Main Results:
- The iFold server supports various simulation types including protein folding, thermal denaturation, and thermodynamic scans.
- Enables p(fold) analysis and simulated annealing.
- Facilitates the study of protein dynamics not easily detectable experimentally.
Conclusions:
- The iFold server provides a powerful, accessible platform for advanced protein dynamics simulations using DMD.
- It aids in understanding protein folding mechanisms and uncovering hidden structural and biological properties.
- This approach bridges critical size and timescale gaps in molecular simulations.

Overview
01:25Protein Folding
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

01:29Protein Folding Quality Check in the RER
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...
03:00Molecular Chaperones and Protein Folding
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
