Some weeks ago, I asked for any information about inhibitors of o-linked
glycosylation. I received 3 replies. (Because the replies were by email,
I will not quote the authors names). Interestingly, they provided rather
Responder#1 said "Apart from a serine or theonine analogue that also blocks
translation, no o-lined glycosylation inhibitors exist"
Responder#2 said "MONENSIN...will interfere with o-linked glycosylases. I
used this drug a number of years ago when characterizing the surface
glycoproteins of human Paramyxovirus III. Monensin is an ionophore that
interferes with many cellular functions:

Responder#3 said referred us to JBC v264 #32 pp19271-19277 (1989) for a
list of other inhibitors.
This looks like a case where some posting directly to this group might be
enlightening to us all! I originally posted this request for a graduate
student, Jot Singh, who is now "on line" and will participate in any
resulting discussion himself. If I can twist his arm, he will follow up
in some weeks with his own results.
