void* __init__(boost::python::api::object,RDKit::MolStandardize::TautomerEnumerator)

Canonicalize((TautomerEnumerator)self, (Mol)mol) → Mol :¶

Returns the canonical tautomer for a molecule.

The default scoring scheme is inspired by the publication: M. Sitzmann et al., “Tautomerism in Large Databases.”, JCAMD 24:521 (2010) https://doi.org/10.1007/s10822-010-9346-4

Note that the canonical tautomer is very likely not the most stable tautomer for any given conditions. The default scoring rules are designed to produce “reasonable” tautomers, but the primary concern is that the results are canonical: you always get the same canonical tautomer for a molecule regardless of what the input tautomer or atom ordering were.

C++ signature :
RDKit::ROMol* Canonicalize(RDKit::MolStandardize::TautomerEnumerator,RDKit::ROMol)

Canonicalize( (TautomerEnumerator)self, (Mol)mol, (AtomPairsParameters)scoreFunc) -> Mol :

Enumerate((TautomerEnumerator)self, (Mol)mol) → TautomerEnumeratorResult :¶

Note: the definitions used here are that the atoms modified during tautomerization are the atoms at the beginning and end of each tautomer transform (the H “donor” and H “acceptor” in the transform) and the bonds modified during transformation are any bonds whose order is changed during the tautomer transform (these are the bonds between the “donor” and the “acceptor”).

C++ signature :: (anonymous namespace)::PyTautomerEnumeratorResult* Enumerate(RDKit::MolStandardize::TautomerEnumerator,RDKit::ROMol)

GetCallback((TautomerEnumerator)self) → object :¶

PickCanonical( (TautomerEnumerator)self, (AtomPairsParameters)iterable, (AtomPairsParameters)scoreFunc) -> Mol :

returns the canonical tautomer for a molecule using a custom scoring function

C++ signature :: RDKit::ROMol* PickCanonical(RDKit::MolStandardize::TautomerEnumerator,boost::python::api::object,boost::python::api::object)

static ScoreTautomer((Mol)mol) → int :¶

SetMaxTransforms((TautomerEnumerator)self, (int)maxTransforms) → None :¶

set the maximum number of transformations to be applied. This limit is usually hit earlier than the maxTautomers limit and leads to a more linear scaling of CPU time with increasing number of tautomeric centers (see Sitzmann et al.).

C++ signature :: void SetMaxTransforms(RDKit::MolStandardize::TautomerEnumerator {lvalue},unsigned int)

SetReassignStereo((TautomerEnumerator)self, (bool)reassignStereo) → None :¶

set to True if you wish AssignStereochemistry to be called on each tautomer generated by the Enumerate() method. This defaults to True.

C++ signature :: void SetReassignStereo(RDKit::MolStandardize::TautomerEnumerator {lvalue},bool)

SetRemoveBondStereo((TautomerEnumerator)self, (bool)removeBondStereo) → None :¶

set to True if you wish stereochemistry information to be removed from double bonds involved in tautomerism. This means that enols will lose their E/Z stereochemistry after going through tautomer enumeration because of the keto-enolic tautomerism. This defaults to True in the RDKit and also in the workflow described by Sitzmann et al.

C++ signature :: void SetRemoveBondStereo(RDKit::MolStandardize::TautomerEnumerator {lvalue},bool)

SetRemoveSp3Stereo((TautomerEnumerator)self, (bool)removeSp3Stereo) → None :¶

set to True if you wish stereochemistry information to be removed from sp3 atoms involved in tautomerism. This means that S-aminoacids will lose their stereochemistry after going through tautomer enumeration because of the amido-imidol tautomerism.
