I have a large list of sequence IDS that I need to download the AA sequences for. Its a mixed bag of Uniprot, Refseq, and NCBI Protein Accession. And the IDs are to a collection of organisms (mostly human but some HIV, HCV, rat, etc.)
Does anyone know of a webtool that can handle a mixed lists of ids and convert them to a single database? I know I can use biomart (or some other tool) to convert everything to a single ID system but I was wondering if there are any tools that can do that step for me.
