This page reads only the latest assembly calculations. Every curve maps to an explicit PDB entry, official biological assembly and coordinate model.

Assembly	Model	Structure unit	Oligomeric description	Status	CRYSOL	Actions
1	1	`3p1j__assembly_1__model_1`	dimeric （2）	Excluded	—	—
	Exclusion reason： The source record does not identify the atom or ion element unambiguously, so a reliable calculation is not possible.
