indicates the Lewis X motif |
|
Fuca1–3(Galb1–4)GlcNAcb |
indicates same motif; either branch may be enclosed |
|
standard abbreviations for monosaccharides |
|
“a” and “b” for α and β, linkages separated by dash or
comma |
|
case insensitive |
angled brackets specify details about the linkage
or monosaccharide |
Neu5AcA2-<3or6>GalB1–4<3f6f>GlcNAcB1–2<4f;6f>ManA |
indicates Neu5Ac either 3′- or 6′-linked to an unbranched LacNAc |
|
<T>Gal |
indicates terminal galactose |
|
the “f” modifier specifies a location
as unoccupied
(free) |
|
an unspecified location
indicates occupied or unoccupied |
|
the OR operator can be used to designate multiple options of
linkage or monosaccharide |
|
the XOR operator can be used to indicate multiple options of
linkage, where all other options of linkage are unoccupied (free) |
|
commas or semicolons can be included
for clarity so that <3f6f>, <3f,6f>, and <3f;6f> are equivalent |
|
the “T”
modifier is shorthand for all nonreducing
locations being unoccupied (<2f3f4f6f> for hexose and <8f9f> for neuraminic
acids) |
special monosaccharide terms are available |
Any??-<3OR6>Galb1–4<3f;6f>GlcNAcb1–2<4f;6f>Mana |
indicates a single monosaccharide extension linked
either 3′ or 6′ to an
unbranched LacNAc |
|
Any??-<3OR6>Galb1–4<3f;6f>GlcNAcb1-?Mana |
indicates
the same but with any linkage to mannose: |
Fuca1-<2or3>Any?1-?Skip??-3(Fuca1-<2or3>Any?1-?Skip??-6)Galb |
indicates a fucose
anywhere on both a 3′ and a 6′
extension of Gal |
|
the “Any”
wildcard is for unspecified monosaccharides |
|
the “?” wildcard is for unspecified
linkages |
|
the “Skip”
modifier indicates a gap of any kind |
|
the “Skip” modifier encompasses lengths of zero,
or no gap |
