  1.0 CODATA Format
  =================
  This document describes the quarterly release of the PIR-International 
  Protein Sequence Database in CODATA format formerly distributed on magnetic
  media for non-VAX/VMS systems in fixed-length 80-byte records.
  
  2.0 In this Release
  ===================
  Release 75.02 of the Protein Sequence Database contains 283,289 entries
  and 96,161,405 residues. The Release is separated into four datasets.
  Section 1, Fully Classified Entries, contains 20,692 entries and
  8,116,023 residues. Section 2, Verified and Classified Entries, contains
  262,166 entries and 87,978,081 residues. Section 3, Unverified Entries,
  contains 24 entries and 74 residues. Section 4, Unencoded or
  Untranslated Entries, contains 407 tries and 67,227 residues. A total
  of 36,307 superfamilies are represented in sections 1 and 2.

  3.0 Features in this felease
  ============================
  Starting with Release 64.00 of the Protein Sequence Database, PIR-International
  is including status information in protein titles, function and complex records.
  These new status identifiers are as follows.
  
  [validated] = in a title or function block means that one of the references
  in the entry contains some experimental evidence for the protein's function.
  
  [similarity] = in a title or function block means that the name and/or 
  function has been assigned by end to end sequence similarity with other 
  entries that have that same name or function.
  
  [imported] = in a title means that the name was imported with the sequence from
  GenBank, EMBL DDBJ, or other source and has not been verified by PIR.
  
  Complete coverage of the entire database will not be obtained for several
  releases.  The absence of a status identifier at this time should NOT be taken
  as an indication that the information in the title or function blocks is not
  correct or has not been evaluated by PIR staff.
