Sažetak
GDP-4-keto-6-deoxy-D-mannose epimerase/reductase is a bifunctional enzyme involved in the biosynthesis of cell-surface structures, such as blood group antigens. Each subunit in the homodimeric enzyme consists of two domains. The N-terminal domain displays a Rossmann-fold topology and binds the NADP+ coenzyme. The C-terminal domain is held to bind the substrate. The holo-enzyme structure has been refined at 1.45 Å resolution, based on synchrotron data, to a final R-factor of 0.127 (Rfree = 0.167). The refined protein model highlights several residues involved in coenzyme recognition and binding and suggests that the enzyme belongs to the short-chain dehydrogenase protein homology family. Implications of the catalytic mechanism are discussed.
