utilities: Translate UniProt taxon names to scientific names, taxids, or...

In Bioconductor/UniProt.ws: R Interface to UniProt Web Services

Translate UniProt taxon names to scientific names, taxids, or domain codes

Description

UniProt uses custom coding of organism names from which protein sequences they store. These taxon names are used also in the protein names (not in the UniProt IDs!). These functions help to translate those names to standard scientific (Latin) taxon names and other useful identifiers.

• taxname2species(): converts UniProt taxonomy names to scientific species names

• taxname2taxid(): converts UniProt taxonomy names to NCBI Taxonomy IDs

• taxname2domain(): converts UniProt taxonomy names to the following taxonomical domains:

  • 'A' for archaea (=archaebacteria)

  • 'B' for bacteria (=prokaryota or eubacteria)

  • 'E' for eukaryota (=eukarya)

  • 'V' for viruses and phages (=viridae)

  • 'O' for others (such as artificial sequences)

Usage

taxname2species(taxname, specfile)

taxname2taxid(taxname, specfile)

taxname2domain(taxname, specfile)

Arguments

taxname	Character string up to 6 uppercase characters, like HUMAN, MOUSE, or AERPX. Also works for a vector of such taxon names.
specfile	An optional local file where speclist.RData is saved from UniProt.org. When specfile is missing, a cached file from the extdata/ package directory is used.

Value

• taxname2species: a character vector of scientific taxon names matching to the UniProt taxon names supplied as taxname.

  • taxname2taxid: a numeric vector of Taxonomy IDs matching to the UniProt taxon names supplied as taxname.

  • taxname2domain: a character vector of one letter domain symbols matching to the UniProt taxon names supplied as taxname.
