O-xylosyl-L-serineGo to external page http://purl.obolibrary.org/obo/MOD_00814
A protein modification that effectively converts an L-serine residue to O3-xylosylserine. [ PubMed : 8747463 https://proteininformationresource.org/cgi-bin/resid?id=AA0406 ]
CARBOHYD O-linked (Xyl) serine
- C 5 H 8 N 0 O 4
- C 8 H 13 N 1 O 6
- 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].
