Hi all,

I have just forwarded the following message to the list as
it had been blocked with a "suspicious header". Could I
remind people please try and send "plain text" emails,
rather than rich HTML formatting with pictures etc as
these are likely to get blocked by the mailing list.

Thanks

Peter

Subject: Finding protein ID using Entrez.efetch

Hi all,

I'm looking for the way to extract the data of protein ID numbers in
the Genbank. I got my Genbank data and save it as a xml file using
this commend.

from Bio import Entrez
handle=Entrez.efetch(db="nuccore",id="256615878",rettype="gb")
record=handle.read()
save_file = open("record.xml","w")
save_file.write(record)
save_file.close()

What I need is all the protein ID (For example: EEU21068.1) or GI
number (for example: 256615878) in this Genbank page for the blast
search. Could you let me know how to extract these information, save
in some format, and use them?

Thank you,
