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 68.04 of the Protein Sequence Database contains 232,581 entries
and 80,595,279 residues. The Release is separated into four datasets.
Section 1, Fully Classified Entries, contains 20,501 entries and
8,042,606 residues. Section 2, Verified and Classified Entries, contains
211,514 entries and 72,458,028 residues. Section 3, Unverified Entries,
contains 85 entries and 27,336 residues. Section 4, Unencoded or
Untranslated Entries, contains 404 entries and 66,362 residues. A total
of 32,106 superfamilies are represented in sections 1 and 2. 

3.0 Features in this Release
============================
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.
