UniProt describes the effects of mutations in proteins' amino acid sequence on the biological properties of the protein, cell or the organism. Using this function, you can search for mutagenesis description in UniProt proteins. You may also refine your search. See "Arguments section" for more information.


  accession = NULL,
  taxid = NULL,
  db_id = NULL,



UniProtKB primary or secondary accession(s). You can supply up to 100 accession numbers.


NIH-NCBI Taxon ID. You can supply up to 20 taxon IDs.


The ID in a Cross-reference (external) database. You can supply up to 20 values.


rbioapi option(s). See rba_options's arguments manual for more information on available options.


A list Where each element correspond to a UniProt protein (search hit) and mutagenesis description are organized under the "features" sub-list.


Note that this is a search function. Thus, you are not required to fill every argument; You may use whatever combinations of arguments you see fit for your query.
