CAZypedia needs your help!
We have many unassigned pages in need of Authors and Responsible Curators. See a page that's out-of-date and just needs a touch-up? - You are also welcome to become a CAZypedian. Here's how.
Scientists at all career stages, including students, are welcome to contribute.

Authors may get an idea of what to put in each field from Curator Approved Glycosyltransferase Families. (TIP: Right click with your mouse and open this link in a new browser window...)
In the meantime, please see these references for an essential introduction to the CAZy classification system: [1, 2].

Catalytic Residues
The large majority of GT1 presents a His-Asp catalytic dyad, acting as a general base. The histidine abstract a proton, increasing the nucleophilicity of the glycosyl acceptor. The aspartate activates the histidine, the abstracted proton being shared almost equally between these two residues.
Three-dimensional structures
GT1 present a GT-B fold,
Family Firsts
Content is to be added here.
