Category Description
Data items in the STRUCT_BIOL category record details about
the structural elements that form each structure of biological
significance.
A given crystal structure may contain many different biological
structures. A given structural component in the asymmetric
unit may be part of more than one biological unit. A given
biological structure may involve crystallographic symmetry.
For instance, in a structure of a lysozyme-FAB structure, the
light and heavy chain components of the FAB could be one
biological unit, while the two chains of the FAB and the lysozyme
could constitute a second biological unit.

1
; significant deviations from twofold symmetry exist in this dimeric
enzyme
;
2
; The drug binds to this enzyme in two roughly twofold symmetric modes.
Hence this biological unit (2) is roughly twofold symmetric to biological
unit (3). Disorder in the protein chain indicated with alternative
id 1 should be used with this biological unit.

3
; The drug binds to this enzyme in two roughly twofold symmetric modes.
Hence this biological unit (3) is roughly twofold symmetric to biological
unit (2). Disorder in the protein chain indicated with alternative
id 2 should be used with this biological unit.
