Remarks
UniProtKB is covered by Thomson Reuters Data Citation Index. is covered by Elsevier. Different databases for different uses: We have built four different databases: The UniProt Knowledgebase, and in particular UniProtKB/Swiss-Prot,
is used to access functional information on proteins. Every UniProtKB entry contains the amino acid sequence, protein name or description,taxonomic data and citation information but in addition to this, we add
as much annotation as possible. This includes widely accepted biological ontologies, classifications and cross-references, as well as clear indications on the quality of annotation in the form of evidence attribution to
experimental and computational data. - The UniRef databases provide clustered sets of sequences from
UniProtKB and selected UniParc records to provide complete coverage of sequence space at several resolutions. UniRef90 and UniRef50 yield a database size reduction of approximately 40% and 65%, respectively, providing significantly faster sequence searches. - UniParc is the most comprehensive publicly accessible non-redundant
protein sequence database available, providing links to all underlying
sources and versions of these sequences. You can instantly find out whether a sequence of interest is already in the public domain and, if not, identify its closest relatives. - UniMES is a repository specifically for metagenomic and environmental
data.
