I'm trying to download some protein sequences using Entrez through command line. However, altough 'esearch' command finds my proteins (searching by ID), the 'efetch' don't return anything. I've tried both gp and fasta formats.
Here are some example IDs:
GCB61038, GCB69151, GCC23899, GCC32047, MXQ86236
I have a list with 457 proteins that I can't download the sequences.
