The "Biopolymer showcase with non-canonical amino acid" follow up workshop to the 5th Open Force Field Workshop, presented by Josh Mitchell of OpenFF. A session on biopolymer support in OpenFF Toolkit 0.11, showing advanced usage by parametrizing 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 introduce the Toolkit's new biopolymer support, and then demonstrate a way to apply a post-translational modification. We look at optimizing charge generation by transferring charges generated from a simpler molecule to our new peptide, and then simulate it in OpenMM!
