  The preparation of deoxy derivatives of mannose-1-phosphate and their substrate specificity towards recombinant GDP-mannose pyrophosphorylase from Salmonella enterica, group B

  摘要：

  2-Deoxy-alpha-D-glucose-1-phosphate, 3-deoxy-alpha-D-arabino-hexose-1-phosphate, 4-deoxy-alpha-D-lyxo-hexose-1-phosphate, and alpha-D-lyxose-1-phosphate were synthesised chemically, and evaluated as substrates for a recombinant GDP-mannose pyrophosphorylase (Salmonella enterica, group B, cloned in Escherichia coli). The deoxy derivatives were all substrates for the enzyme, with slightly reduced V-max values but significantly higher K-m values than those recorded for the native substrate, mannose-1-phosphate. The pyrophosphorylase was used for the synthesis of GDP-mannose analogues GDP-2-deoxy-glucose and GDP-lyxose on a milligram scale. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Glucose-responsive insulin conjugates that contain one or more trisaccharides are provided. Such insulin conjugates may display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose, even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule.
