Is there a way to separate the chains belong to each Biological assembly in a PDB file?

Question

[Christian]

I want to separate the chain IDs which belong to specific Biological assemblies in a PDB file. As an Example PDB ID 1BRS has 3 Biological assemblies Biological assembly 1 : - chains A and D Biological assembly 2 : - Chains B and E Biological assembly 3 : - chains C and F

Is there a way (python Script) to get the Chain IDs separate which belong to each biological assembly as follows 1BRS_A:D 1BRS_B:E 1BRS_C:F No need to extract the chain coordinates. If I get the chain names, that will be enough. Thanks in advance

I believe you might be able to do this with biopython's PDB methods. Alternatively you can do this (GUI or commandline), by hooking in to UCSF Chimera's object model.

I don't know of any pre-existing solutions though.

You can get biological assembly information from pdb databases(e.g. PDBe, RCSB).
