I know that similar questions have been asked here, but I still haven't found a fitting answer.
I need to download all the nucleotide sequences of a specific gene of a virus from GenBank. Not only it is difficult to find the published sequences of the gene itself, but I would also like to find the ones within whole genomes (annotated ones of course).
For instance, let's say I need all nucleotide sequences of the "EBNA-1" gene of the Human Herpesvirus 4. Is there a way to download a fasta of all published EBNA-1s, included the ones annotated in complete genomes? The number of sequences I'm looking at are way too much to do it manually, but all serache I did give me sequences of almost random organisms. I have been mainly used the NCBI website to test the searches, and eUtils (esearch and efetch) for the downloads.
Thanks a lot in advance.
