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 70.03 of the Protein Sequence Database contains  entries
and  residues. The Release is separated into four datasets.
Section 1, Fully Classified Entries, contains 20,709 entries and
8,119,290 residues. Section 2, Verified and Classified Entries, contains
241,389 entries and 81,532,256 residues. Section 3, Unverified Entries,
contains 23 entries and 69 residues. Section 4, Unencoded or
Untranslated Entries, contains 404 tries and 66,362 residues. A total
of 32,933 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.
