Data items in the PDBX_STRUCT_ASYM_GEN category record details about
the generation of the crystallographic asymmetric unit. The
PDBX_STRUCT_ASYM_GEN data items provide the specifications of the
components that constitute the asymmetric unit in terms of cartesian
transformations of deposited coordinates.
