Glycan database include sugar connect with 3 child sugar?

Opened this issue 6 years ago · 4 comments

I guess glycan represented as a binary tree string format in pGlyco such as: (N(N(H(H)(H(H(H)))))). No sugar is connected to more than 2 child sugars. Does the glycan database include something not binary like this (https://glytoucan.org/Structures/Glycans/G40806JH)?

I would guess based on what I understand from the user guide page 24 (http://pfind.ict.ac.cn/software/pGlyco/pGlyco2.1.2%20User%20Guide.pdf) that it will be something like:

(F(N(N(H(H(H)(H))(N)(H(N(H)))))))

Yes, bisecting HexNAc is in our glycan database.

For example, (N(N(H(N)(H(N)(N))(H(N(H)))))).

This must be the structure. This is really a neat and powerful method to represent glycan. Thanks!
