comment
  • One glycosylated serine with weak electron density was modeled as O3-alpha-xylosylserine, while O3-alpha-mannosyl serine and threonine were modeled at ten other positions. The authors do not discuss this exception or provide chemical evidence for it. Since an O3-xylosyl serine modification has not been reported in any other fungal proteins, the modification is probably also an O3-alpha-mannosyl serine, see MOD:00810 [JSG].
