Abstract

âº First detailed model of donor substrate binding for human fucosyltransferase FUT8. âº Model is based on X-ray structures combined with ligand-based NMR data and SPR data. âº Refinement with molecular dynamics simulation yields substrate binding mode. âº Major donor binding of FUT8 originates from Î²-phosphate group. âº The key catalytic residue Arg365 orientates fucose residue and assists GDP release.
