Unable to make OFFMol from RDMol: RDMol has unspecified stereochemistry

[suice07]

Hello everyone,

I am creating Molecule object from a rdkit mol,with a conformer file,ligand.mol2 and a protein file 5x1a.pdb, after merging it to a complex file 5x1a_complex.pdb, it is impossible to generate Molecule object in this way.

smi` = 'CC1=NN(c2ccc(C)c(C)c2)C(=O)/C1=N\\Nc1cccc(-c2cccc(C(=O)O)c2)c1O'
rdkit_mol = Chem.MolFromPDBFile('test04192/5x1a_complex.pdb')
rdkit_mol_split = Chem.rdmolops.SplitMolByPDBResidues(rdkit_mol)
ligand = rdkit_mol_split['UNL']
ligand = Chem.RemoveHs(ligand)
reference_mol = Chem.MolFromSmiles(smi)
prepared_ligand = AllChem.AssignBondOrdersFromTemplate(reference_mol, ligand)
prepared_ligand.AddConformer(ligand.GetConformer(0))
prepared_ligand = Chem.rdmolops.AddHs(prepared_ligand, addCoords=True)
off_mol = Molecule.from_rdkit(rdkit_mol)

Traceback (most recent call last):

Here is the error. I am having the openff-toolkit==0.10.7,how could I generate the Molecule object correctly.

Hiya! The problem is most likely that your molecule has undefined stereochemistry - it's difficult to be more specific without seeing the PDB you're loading. The OpenFF Toolkit requires all molecules to have fully defined stereochemistry to reduce errors - we've made a virtue of being very strict about what we can put in a Molecule. Just having coordinates that specify stereochemistry isn't enough, it actually needs to be defined on the molecular graph.

You can try inferring stereochemistry from the PDB coordinates, or you can create a Molecule without stereochemistry at the risk of missing out on force field parameters that specify stereochemistry with off_mol = Molecule.from_rdkit(rdkit_mol, allow_undefined_stereo=True)

Thanks so much for the quick reply, I think from PDBfile, some bond information is missing, so I tried to generate ff using another way,but come with this error,is this still means the stereochemistry information is missing so that no tool can be used to generate forcefield?or it is because the ligand is name is unknown acid, so it is not able to generate forcefield?

It looks like you've successfully got the molecule into the Toolkit but AmberTools doesn't like it for some reason. Could you provide the output of conda list in the environment where you got that error, and also all the code you ran and input files you used to get that error?

        Use pdbfixer to prepare the protein from a PDB file. Hetero atoms such as ligands are
        removed and non-standard residues replaced. Missing atoms to existing residues are added.
        Missing residues are ignored by default, but can be included.

        Parameters
        ----------
        pdb_file: pathlib.Path or str
            PDB file containing the system to simulate.
        ignore_missing_residues: bool, optional
            If missing residues should be ignored or built.
        ignore_terminal_missing_residues: bool, optional
            If missing residues at the beginning and the end of a chain should be ignored or built.
        ph: float, optional
            pH value used to determine protonation state of residues

I have no idea about how to fix that,now . Maybe I am having too many transformations so it is hard for the toolkit to continue the job?

[mattwthompson]

Something is wrong with how RDKit parses that file and/or how the RDKit molecule is prepared. If all you need is the molecule loaded up from SMILES anyway, the toolkit offers a more direct way of handling that in addition to many other pathways.

I can assign partial charges from that SMILES pattern without issue using the most recent version of OpenFF tools and dependencies, although it takes a while since AM1 is slow.

from openff.toolkit import Molecule

molecule = Molecule.from_smiles("CC1=NN(c2ccc(C)c(C)c2)C(=O)/C1=N\\Nc1cccc(-c2cccc(C(=O)O)c2)c1O")
molecule.assign_partial_charges(partial_charge_method="am1bcc")

Note also that you're using an old version (0.10.3) of the toolkit which won't be supported for much longer. Newer versions include a plethora of bugfixes useful features, such as loading PDB files directly.
