I am using entrez to fetch the sequence of the protein. This will thive me the fasta sequence. https://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=protein&id=16128551&rettype=fasta&retmode=text
But I want to have the GI number on the comment line along with the sequence. What modification should I so to get that if it is possible?
