biotite.structure.filter_nucleotides¶
- biotite.structure.filter_nucleotides(array)[source]¶
Filter all atoms of one array that belong to nucleotides.
- Parameters
- arrayAtomArray or AtomArrayStack
The array to be filtered.
- Returns
- filterndarray, dtype=bool
This array is True for all indices in array, where the atom belongs to a nucleotide.
Notes
Nucleotides are identified according to the PDB chemical component dictionary. A residue is considered a nucleotide if it its
_chem_comp.type
property has one of the following values (case insensitive):DNA LINKING
,DNA OH 3 PRIME TERMINUS
,DNA OH 5 PRIME TERMINUS
,L-DNA LINKING
,L-RNA LINKING
,RNA LINKING
,RNA OH 3 PRIME TERMINUS
,RNA OH 5 PRIME TERMINUS
