To improve security and privacy, we are moving our web pages and services from HTTP to HTTPS.
To give users of web services time to transition to HTTPS, we will support separate HTTP and HTTPS services until the end of 2017.
From January 2018 most HTTP traffic will be automatically redirected to HTTPS. [more...] View this page in https
is a tool which allows the comparison of the amino acid
composition of a UniProtKB/Swiss-Prot entry with all other UniProtKB/Swiss-Prot entries so as
to find the proteins whose amino acid compositions are closest to that of
the selected entry [references
You will have to enter the following data:
- A UniProtKB/Swiss-Prot identifier (ID) (e.g. ALBU_HUMAN) or UniProtKB/Swiss-Prot
accession number (AC) (e.g. P04406).
- Your e-mail address. The search results will be mailed back to you
automatically (this should take less than 15 minutes).
- The UniProtKB/Swiss-Prot abbreviation for the species for which you would like to perform the search (example:
HUMAN). This will produce the list of proteins from this species, as
well as a list of proteins independently of species; you may also
specify ALL for all UniProtKB/Swiss-Prot entries.
Few amino acid analysis techniques produce composition results for all
amino acids. We currently have indexed UniProtKB/Swiss-Prot for the following
constellations. Please choose one of them:
- Constellation 0:
ALL amino acids: Ala, Ile, Pro, Val, Arg, Leu, Ser, Thr, Gly, Met, His, Phe, Tyr, Lys, Asp, Asn, Gln, Glu,
Cys and Trp.
- Constellation 1:
Ala, Ile, Pro, Val, Arg, Leu, Ser, Asx, Thr, Glx, Gly, Met, His, Phe and Tyr.
(Asp+Asn=Asx; Gln+Glu=Glx; Lys, Cys and Trp are not considered).
- Constellation 2:
Ala, Ile, Pro, Val, Arg, Leu, Ser, Asx, Lys, Thr, Glx, Gly, Met, His, Phe and
(Asp+Asn=Asx; Gln+Glu=Glx; Cys and Trp are not considered).
