Název v původním jazyce

Three-dimensional homology model of GlcNAc-TV glycosyltransferase

Popis výsledku v původním jazyce

The enzyme UDP-N-acetylglucosamine: a-d-mannoside b-1-6 N-acetylglucosaminyltransferase V (GnT-V) catalyzes the transfer of GlcNAc from the UDP-GlcNAc donor to the a-1-6-linked mannose of the trimannosyl core structure of glycoproteins to produce the b-1-6-linked branching of N-linked oligosaccharides. b-1-6-GlcNAc-branched N-glycans are associated with cancer growth and metastasis. Therefore, the inhibition of GnT-V represents a key target for anti-cancer drug development. However, the development of potent and specific inhibitors of GnT-V is hampered by the lack of information on the three-dimensional structure of the enzyme and on the binding characteristics of its substrates. Here we present the first 3D structure of GnT-V as a result of homology modeling. Various alignment methods, docking the donor and acceptor substrates, and molecular dynamics simulation were used to construct seven homology models of GnT-V and characterize the binding of its substrates.
