Category STRUCT_REF_SEQ

Name:
'struct_ref_seq'

Description:

   Data items in the STRUCT_REF_SEQ category provide a mechanism
   for indicating and annotating a region (or regions) of alignment
   between the sequence of an entity or biological unit described
   in the data block and the sequence in the referenced database
   entry.

Example:

Example 1 - based on the sequence alignment of CHER from M. xantus (36 to 288) and CHER from S. typhimurium (18 to 276).
