Thanks a lot, Jon. The resolution is very low (3.1Å) and the density is confusing, I was trying to rule out things.

I am not an expert in glycoproteins, if a boat GlcNAc is this extremely unlikely, I will try other things...😉.

I would be very, very surprised to find such a thing in a crystal structure of a glycoprotein. What's the resolution of the data?

    Dear all,

    has anybody ever seen a GlcNAc in boat conformation attached to an
    asparagine and, if so, is there any reference for it?

    Thanks a lot in advance,

    Xavier
