| Abstract |
N-acetylglucosaminyltransferase-V (GnT-V or MGAT5) is a glycosyltransferase involved in cancer metastasis that creates the β1,6-branch on N-glycans of target proteins such as cell adhesion molecules and cell surface receptors. The 3D structure of GnT-V and its catalytic site, which are critical for the interaction with the N-glycan terminal, have already been revealed. However, it remains unclear how GnT-V recognizes the core part of N-glycan or the polypeptide part of the acceptor. Using molecular dynamics simulations and biochemical experiments, we found that several residues outside the catalytic pocket are likely involved in the recognition of the core part of N-glycan. Furthermore, our simulation suggested that UDP binding affects the orientation of the acceptor due to the conformational change at the Manα1,6-Man linkage. These findings provide new insights into how GnT-V recognizes its glycoprotein substrates. |
