This describes how to unfold whole or parts of chains in solved structures using Pymol. This maintains the covalent bonds. Also below is how to alter disulfide bonds in a structure using Pymol. | This describes how to unfold whole or parts of chains in solved structures using Pymol. This maintains the covalent bonds.

See [https://www.biostars.org/p/9588134/#9589058 my answer here to 'How can I linearize certain residues within an existing protein structure to create a dumbbell-shaped structure?'] for an option to do this in a scripted in PyMOL or automated way with PyMOL by setting dihedral angles for a span of amino acids to represent an unfolded state. Importantly, you can do with an PDB that has a protein chain by specifying the PDB id code and chain and region without needing to install anything on your system. | |||
Below is the older way of doing this with Auto-Sculpting in PyMOL... | |||
This came up because [https://people.chem.umass.edu/cbobst/Members.html Adriana Zeledon] wanted to generate structures derived from her structure of interest where parts were unfolded or folded differently. I thought this could very useful for illustrative or conceptualizing purposes for many users. For maybe simulating denaturing, conformational changes, or other dynamic processes. | This came up because [https://people.chem.umass.edu/cbobst/Members.html Adriana Zeledon] wanted to generate structures derived from her structure of interest where parts were unfolded or folded differently.
