Structure of TrCel7A with labeled N-glycosylation sites. The structure of TrCel7A is shown as the grey surface, N-glycans as the blue/red sticks, O-glycans as the yellow/red sticks and the cellulose as the green surface. All of the experimentally determined N-glycosylation sites in this study are presented here: N45, N270 and N384. The cartoon representation was modeled in PyMol and it is based on the TrCel7A structure (PDB entry 4C4C) [14]. The cellulose structure was constructed using Cellulose-Builder [15]
