I'm very new to protein modeling work, but from my understanding IgG1 Fcs have a glycan between the CH2 and CH3 domains. I downloaded an IgG1 Fc from the pdb database, but I can't seem to see where it is visually. What does it look like and if I open up the pdb as a text file, what symbol would it be and how would I locate it? Also if I'm doing homology modeling with one as a template, would I have to later add in the Glycan after the model is produced? If so how would I do that?
