The "4m05" likely refers to a , which is a unique four-character identifier for a specific 3D biological macromolecular structure. 🧪 Key Feature: The 4M05 Structure

: 4M05 represents a crystal structure of the human RARβ ligand-binding domain.

are you trying to use it with? (e.g., PyMOL, Chimera, or a compression tool?)

: It might be a collection of "Rapid Access Recording" (RAR) data, though in the context of "4m05," the protein structure is the most scientifically relevant link. To help you find more specific details, could you tell me:
