I have a table with 300 Uniprot entries from mass analysis and want to have the sequence data for each of the entries. Is there a tool with which that can be done automatically?
If it's Gene or Protein identifiers you can go on my tool www.proteinside.com
Past your IDs on the custom analysis and run. When it's finish you can download a fasta file with all protein sequences of your IDs (ID Mapping section of the results).
