Ubiquitin is a small protein consisting of 76 amino acids that binds to lysine residues of substrates, usually by a combination of three enzymes: a ubiquitin-activating enzyme (E1, two types), a ...

Specific glycans attached to the GnT-IVa and GnT-IVb can bind to the enzyme’s ligand-binding site, interfering with recognition and binding to the glycosylation proteins’ normal glycoprotein ...
