Nucleotide sugars are considered as bottleneck and expensive substrates for enzymatic glycan synthesis using Leloir-glycosyltransferases. Synthesis from cheap substrates such as monosaccharides is accomplished by multi-enzyme cascade reactions. Optimization of product yields in such enzyme modules is dependent on the

A standard hybridoma fusion technique was used to produce a monoclonal antibody capable of binding both carcinoembryonic antigen (CEA) and the hapten 4-amino-phthalate. A hypoxanthine-aminopterin-thymidine (HAT) sensitive anti-CEA hybridoma and KLH-phthalate immunized spleen cells were hybridized to yield clones producing

The broad substrate spectrum of UDP-sugar pyrophosphorylases from plant salvage pathways is of high interest for the synthesis of expensive nucleotide sugars by straightforward enzyme cascade reactions in combination with monosaccharide kinases. We here present a new UDP-sugar pyrophosphorylase from
