PDBePISA Get Assemblies

Get predicted biological assemblies from a crystal structure using PDBePISA. Analyzes crystal packing to predict the most likely biological assembly (monomer, dimer, tetramer, etc.) with stability scores, dissociation energy, accessible/buried surface areas, and composition. Use after structure retrieval from RCSB/PDBe to determine the biologically relevant oligomeric state. Positive dissociation energy indicates a stable assembly.
