Amino acids flanking validated N-glycosylation sites. The relative occurrence of amino acids is plotted versus sequence position −6 to +6 around an occupied N-glyc site. Residues specified by the glycosylation sequon (0 = Asn; +2=Ser or Thr) are not plotted. Hydrophobic (Ala, Val, Leu, Ile, Met); Aromatic (Phe, Tyr, Trp); Polar uncharged (Ser, Thr, Asn, Cys, Gln); Acidic (Asp, Glu); Basic (Lys, Arg, His); Unique (Gly, Pro)
