[reaction: see text] An efficient route for the synthesis of orthogonally protected l-sugars has been opened up, starting from the heterocyclic homologating agent 1 and 2,3-O-isopropylidene-l-glyceraldehyde (2). Our synthetic path enables the synthesis of a 2,3-unsaturated-l-pyranoside, which can be suitably

Cellobiose 2-epimerase (CE) reversibly converts glucose residue to mannose residue at the reducing end of β-1,4-linked oligosaccharides. It efficiently produces epilactose carrying prebiotic properties from lactose, but the utilization of known CEs is limited due to thermolability. We focused on

A putative N-acyl-D-glucosamine 2-epimerase from Caldicellulosiruptor saccharolyticus was cloned and expressed in Escherichia coli. The recombinant enzyme was identified as a cellobiose 2-epimerase by the analysis of the activity for substrates, acid-hydrolyzed products, and amino acid sequence. The cellobiose 2-epimerase
