GDP 4-KETO-6-DEOXY-D-MANNOSE EPIMERASE REDUCTASE Y136E

Overview

GDP-4-keto-6-deoxy-d-mannose epimerase/reductase is a bifunctional enzyme, responsible for the last step in the biosynthesis of GDP-l-fucose, the, substrate of fucosyl transferases. Several cell-surface antigens, including the leukocyte Lewis system and cell-surface antigens in, pathogenic bacteria, depend on the availability of GDP-l-fucose for their, expression. Therefore, the enzyme is a potential target for therapy in, pathological states depending on selectin-mediated cell-to-cell, interactions. Previous crystallographic investigations have shown that, GDP-4-keto-6-deoxy-d-mannose epimerase/reductase belongs to the, short-chain dehydrogenase/reductase protein homology family. The enzyme, active-site region is at the interface of an N-terminal NADPH-binding, domain and a C-terminal ... [(full description)]
