Follow-up workshop: Biopolymer showcase and covalent modification example

Abstract

A session on biopolymer support in OpenFF Toolkit 0.11, showing advanced usage by parameterizing a protein with a post-translational modification (PTM). This workshop demonstrates loading and parametrizing biopolymers with the OpenFF Toolkit, including a preview of support for a non-canonical amino acid. We'll introduce the Toolkit's new biopolymer support, and then demonstrate a way to apply a post-translational modification. We'll look at optimizing charge generation by transferring charges generated from a simpler molecule to our new peptide, and then simulate it in OpenMM!

Attendee preparation/install instructions

These instructions assume you have Conda installed already.

  1. Download the materials from the Gist below, either from the “Download ZIP” button or through git clone https://gist.github.com/66007cb9966b1455a259baaf7cd7e7c3.git

  2. Extract the ZIP file, if used, and change directory into the appropriate directory

  3. Create a temporary Conda environment in the working directory: conda env create --prefix ./env --file environment.yml

  4. Run the notebook from the temporary environment: conda run --prefix ./env --no-capture-output jupyter notebook ncaa_parametrization.ipynb

Alternatively, the notebook can be followed and executed online on Binder: https://mybinder.org/v2/gist/Yoshanuikabundi/66007cb9966b1455a259baaf7cd7e7c3/HEAD
