Item Description

The descriptor that categorizes the type of the conformation of the backbone of the polymer (whether protein or nucleic acid). Explicit values for the torsion angles that define each conformation are not given here, but it is expected that the author would provide such information in either the _struct_conf_type.criteria or _struct_conf_type.reference data items, or both.
