biotite.database.rcsb.StructureQuery

class biotite.database.rcsb.StructureQuery(pdb_id, chain=None, assembly=None, strict=True)[source]

Bases: SingleQuery

A query for protein/DNA/RNA molecules with structural similarity to the query structure.

Either the chain or assembly ID of the query structure must be specified.

Parameters:
pdb_idstr

The PDB ID of the query structure.

chainstr, optional

The chain ID (more exactly asym_id) of the query structure.

assemblystr, optional

The assembly ID (assembly_id) of the query structure.

strictbool, optional

If true, structure comparison is strict, otherwise it is relaxed.

Examples

>>> query = StructureQuery("1L2Y", chain="A")
>>> print(sorted(search(query)))
['1L2Y', '1RIJ', '2JOF', '2LDJ', '2M7D', '7MQS']
get_content()

Get the query content, i.e. the data belonging to the 'query' attribute in the RCSB search API.

This content is converted into JSON by the search() and count() methods.
