Abstract

Key Points Glycosylation at N1574 stabilizes the VWF A2 domain against unfolding and proteolysis by ADAMTS13, and its first GlcNAc is the critical element. Y1544 is a likely interacting residue with N1574-GlcNAc, and its mutation to aspartic acid stabilizes the domain in the absence of the glycan.
