Path B - Module 50: Virtual Forms & Memory I/O

Industrial automation often requires processing molecules without touching the hard drive. In this module, you will learn to load PETase mutants from web strings and process them entirely in RAM.

import molsysmt as msm
import requests

# Download PDB content for a PETase variant (e.g., 5XJH)
response = requests.get("https://files.rcsb.org/view/5XJH.pdb")
pdb_text = response.text

# Load from memory using 'string:pdb_text'
molsys = msm.convert(pdb_text, from_form='string:pdb_text', to_form='molsysmt.MolSys')
print(f"Loaded {msm.get(molsys, element='system', n_atoms=True)} atoms from a text variable.")
