 ## Summary
 
 ProtGraph in short is a python-package, which allows to convert protein-entries from the [UniProtKB](https://www.uniprot.org/) to so-called protein-graphs. We use the [SP-EMBL-Entries](https://web.expasy.org/docs/userman.html), provided by UniProtKB via `*.txt` or `*.dat`-files, and parse the available feature-information. In contrast to a FASTA-file-entry of a protein, a SP-EMBL-file-entry is
