This question follows from another question - How To Retrive A Batch Of Transmembrane Domains From Uniprot? - that asks about how to retrieve transmembrane (TM) domains from uniprot.
The top answer in that question mentions that the UniProt XML format can be used to retrieve a fasta sequence of each TM region.
filenames = ["O43561.xml", "P08195.xml", "Q58CT8.xml"] input_format = "uniprot-xml" feature_type = "transmembrane region" output_filename = "uniprot_tm.fasta"
How can this XML snippet be used as part of a python script (without using biopython modules - How To Retrive A Batch Of Transmembrane Domains From Uniprot? - or Java modules - How To Retrieve Human Proteins Sequence Containing A Given Domain - as they have already been solved) to download fasta formatted files from uniprot?
