design-interface-analysis

To analyze protein-protein interfaces and calculate buried surface area, load a designed complex in PyMOL and run the interface-analysis workflow to identify interface residues across A/B chains and compute BSA.

When characterizing binding interfaces in designed protein complexes, the analysis identifies hydrogen bonds, salt bridges, and hydrophobic contacts to annotate stabilizing interactions at the interface.

Yes, you can compare designed protein interfaces against reference complexes using PyMOL scripting, which provides workflow-compatible interface comparison workflows to contrast binding interactions and buried surface area.

To identify binding hotspot contacts, the workflow requires PyMOL with a working scripting interface and compatibility with outputs from RFdiffusion-viz, alphafold-validation, and binding-site-visualization tools.

Buried surface area computation for protein-ligand binding site visualization works by quantifying the surface area obscured upon complex formation, providing design feedback on the strength and quality of the binding interface.

Interface residues may not be selected correctly in PyMOL if the designed complex lacks proper chain definitions or if the inputs from AF2-Multimer or binding-site-visualization are incompatible with the scripting interface.
