1. INTRODUCTION
1.1 Evolution
Release 12.0 of SWISS-PROT contains 12305 sequence entries, comprising
3'797'482 amino acids abstracted from 12147 references. This represents
an increase of 16% over release 11.0. The recent growth of the data bank
is summarized below:

1.2 Source of data
Release 12.0 has been updated using protein sequence data from release
21.0 of the PIR (Protein Identification Resource) protein data bank, as
well as translation of nucleotide sequence data from release 20.0 of the
EMBL Nucleotide Sequence Data Library.
As an indication to the source of the sequence data in the SWISS-PROT
data bank we list here the statistics concerning the DR (Databank
Reference) pointer lines:
Entries with pointer(s) to only PIR entri(es): 3125
Entries with pointer(s) to only EMBL entri(es): 4873
Entries with pointer(s) to both EMBL and PIR entri(es): 3575
Entries with no pointers lines (entered in house): 732
2. DESCRIPTION OF THE CHANGES MADE TO SWISS-PROT SINCE RELEASE 11
2.1 Sequences and annotations
Some 1466 new sequences have been added since the last release, the
sequence data of 173 existing entries has been updated and the
annotations of 2400 entries have been revised. In particular we have
used reviews articles to update the annotations of the following groups
or families of proteins:
Acyl carrier proteins
Aminoacyl-transfer RNA synthetases
Biotin-requiring enzymes
Chloroplast photosystems I and II proteins
Creatine kinases
Crp bacterial activator proteins
Enolases
Glucose-6-phosphate dehydrogenases
Glutaredoxins
GTP-binding elongation factors
Heat shock hsp90 proteins
Insulin family proteins
Insulin-like growth factor binding proteins
Insect-type alcohol dehydrogenases / ribitol dehydrogenase family
Integrins
Iron-containing alcohol dehydrogenases
LysR bacterial activator proteins
Malate dehydrogenase
Mammalian defensins
Mitochondrial energy transfer proteins
Myc-type proteins
Phosphoglucose isomerases
Phosphoglycerate kinases
Serine/threonine specific protein phosphatases
Sugar transporters
Uracil-DNA glycosylases
Vertebrate galactoside-binding lectins
Zinc-containing alcohol dehydrogenases
2.2 New line-type
This release introduce an new type of data line, the OG line. The OG
(OrGanelle) lines indicate if the gene coding for a protein originates
from the mitochondria, the chloroplast, or a plasmid. The format for the
OG line is:
OG CHLOROPLAST.
OG MITOCHONDRION.
OG PLASMID name.
Where 'name' is the name of the plasmid.
Previously this information was stored in the OS line, as shown in the
example below.
OS WHEAT (TRITICUM AESTIVUM) CHLOROPLAST.
The above example will now be stored as:
OS WHEAT (TRITICUM AESTIVUM).
OG CHLOROPLAST.
2.3 New topic for the comments (CC) line type
As of release 12 we have added a new 'topic' for the comments (CC) line-
type: CAUTION, which is used to warn about possible errors and/or
grounds for confusion. Example of its usage:
CC -!- CAUTION: ALSO SEE VERSION 2 OF THIS PROTEIN THAT DIFFERS DUE
CC TO A FRAMESHIFT.
2.4 Documentation changes
- ACINDEX.TXT is a new document file which is an index of all the
accession numbers which appear in SWISS-PROT and the name of the
entries in which they occur.
- PDBTOSP.TXT is a new document file which is an index of all the
Brookhaven PDB entries referenced in SWISS-PROT.
- The JOURLIST.TXT document now indicates the abbreviation and the full
names of all journals cited in SWISS-PROT.
3. THE NEXT RELEASE
SWISS-PROT release 13.0 will be available in January 1990.
Starting with release 13 SWISS-PROT will be distributed with PROSITE, a
data bank of sites and patterns in proteins. Both data banks will be
fully cross-referenced.
4. WE NEED YOUR HELP !
We welcome any feedback from our users. We especially would appreciate
that you notify us if you find that sequences belonging to your field of
expertise are missing from the data bank. We also would like to be
notified about annotations to be updated, as for example if the function
of a protein has been clarified or if new post-translational information
has become available.
