General Information

General Information Comment Organism
evolution bifunctional UDP-glucose 4-epimerases, UGEs, with UDP-xylose 4-epimerase (EC 5.1.3.5) activity are conserved in vascular plants Albuca bracteata
physiological function the enzyme is involved in the biosynthesis of anti-tumor polysaccharides in Ornithogalum caudatum. UGE also plays a key role in carbohydrate partitioning, plant growth and development. Enzyme UGE is important in the composition of the sugar nucleotide pools Albuca bracteata
