Talk:GTC

GlyTouCan motifs are imported directly from the GlyTouCan triple-store using the SPARQL query:

       PREFIX glycan: <http://purl.jp/bio/12/glyco/glycan#>
       PREFIX glytoucan: <http://www.glytoucan.org/glyco/owl/glytoucan#>
       PREFIX rdfs: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
       PREFIX rdf: <http://www.w3.org/2000/01/rdf-schema#>
       
       SELECT DISTINCT ?primary_id ?label ?redend
       WHERE {
           ?Saccharide glytoucan:has_primary_id ?primary_id . 
           ?Saccharide rdfs:type glycan:glycan_motif . 
           ?Saccharide rdf:label ?label .
           ?Saccharide glytoucan:is_reducing_end ?redend
       }

Note that the motif "count" here is one more than shown on the GlyTouCan motifs page - there is an extra motif (GTC.G54161DR) for Heparin (other one is GTC.G00021MO).

GlyTouCan motif accessions are the GlyTouCan accessions of the structures.

GlyTouCan motifs provide a reducing end boolean for each motif, but no aglycon value(s).
