I looked in my biochemistry textbook, but I couldn't find anything really
specific on glycosylation reactions. However, I'm guessing that the protein
may bind to the UDP constituent of UDP-glucose, phosphorylate UDP-glucose to
release glucose and produce UTP, and then the Arg residue probably binds the
glucose via N-glycosylation. I'm not sure of this, but I think it might be
a start. Also, since many glycosylated proteins bear oligosaccaride, this
may be a repeating chain reaction, but I do not have any idea how the
reaction would be terminated.
Again, this is just an educated guess so let me know if this helps,
preferable by email.

Anybody has an idea what the chemistry of following reaction would be?:
The glycosylation of an Arginine amino acid with the glucose from
I have a protein that can bind UDP-glucose and glycosylate itself at an
Arginine and I am trying to figure out how this can take place.
Any ideas or a source of information regarding this question is
