GlycoMod Tool

GlycoMod is a tool that can predict the possible oligosaccharide structures that occur on proteins from their experimentally determined masses. The program can be used for free or derivatized oligosaccharides and for glycopeptides [Documentation / Mass values / Reference / Disclaimer].

Note: You can use GlycanMass to calculate the mass of an oligosaccharide structure from its oligosaccharide composition.

Enter a list of experimental masses:		All mass values are average or monoisotopic.
Or upload a file, containing one mass per line, from your computer:		Mass tolerance: +/-

Ion mode and adducts:

positive	negative	neutral
[M+H]⁺	[M-H]^-	[M]
Na⁺ or K⁺	acetate or trifluoroacetic acid
other: mass:	other: mass:

N-linked oligosaccharides

O-linked oligosaccharides

Form of N-linked oligosaccharide:

Form of O-linked oligosaccharide:

if 'Glycopeptides', please specify:

A protein sequence or a Swiss-Prot/TrEMBL ID or AC:

Enzyme:
max. missed cleavage sites (MC).
Cysteines treated with:
acrylamide adducts on cysteines methionines oxidized

Alternatively, you can also enter a set of unmodified peptide masses ([M]). These masses must be average or monoisotopic in agreement with that specified above for experimental masses:

if 'Derivatised oligosaccharides', please specify: reducing terminal derivative : , mass:

Monosaccharide residues present (if known):
Monosaccharide residues are: underivatised permethylated peracetylated.

		range (if known):
Hexose (e.g. Man, Gal)		-
