Graphical Interface

To search registered glycans with a specific structural fragment, it is possible to build through a graphical interface as shown in the figure. The tool used is based on the work done for GlycanBuilder with Vaadin as described in

Damerell D, Ceroni A, Maass K, Ranzinger R, Dell A, Haslam SM. The GlycanBuilder and GlycoWorkbench glycoinformatics tools: updates and new developments. Biol Chem. 2012;393:1357–1362. PubMed.

It is possible to create or extend from existing structures within this interface.


Glytoucan Graphical Interface

Note: User registration is not required to query for a structure.


Once the structure is complete, a sequence is generated from the input and used to search the database for a valid id. If the sequence is found, the structure format and any related super structures will be displayed.


Glytoucan Graphical Interface Results

Result page of the search. Other glycans containing the input structure will also be displayed.
