Usability Domain
  List of Glycans identified by GlyTouCan Accessions with infomation on the mouse[taxid:10090] proteins involved in the synthesis of the glycan.

Description Domain
  Description: This file contains 39 proteins involved in the synthesis of 2146 GlyTouCan accession. The protein(enzyme) to glycan assignment is calculated based on a "glyco-tree" model.
  Keywords: GlyTouCan, Glycan, Enzyme, Synthesis
  
  Pipeline Steps:
    Step 1: The input file was downloaded from the source link and the 'Enzyme:UniProtAccession' column was mapped to canonical accession using a python script [ac2canonical.py].
