Proposed products formed using trehalose phosphorylase. (A) Euglena trehalose phosphorylase was able to make glycosides (product number in brackets) by transfer of d-glucose onto d-glucose (forming 1), 6-deoxy-d-glucose (13) and d-xylose (14). 14 (B) Thermoanaerobium trehalose phosphorylase was able to transfer glucose onto d-galactose (15), d-mannose (16), l-arabinose (17), l- (18) and d- (19) fucose, d-glucosamine (20), N-acetyl-d-glucosamine (21) and 2-deoxy-d-glucose (22). 16 These latter experiments only assess Pi release from d-Glc-1-P by the phosphorylase in the presence of these acceptors; product structures have not been confirmed.
