Abstract

Novel fluorogenic 2-deoxy-2-fluoroglycosyl acridinone active site titrating reagents were synthesised and kinetic parameters determined for their inactivation of two retaining β-glucosidases, a β-galactosidase, a β-xylosidase and several cellulases. Fluorescence-monitored active site titration using this class of reagents reliably measured active enzyme concentrations down to 3 nM.

摘要

合成了新型荧光2-脱氧-2-氟糖基吖啶酮活性位点滴定试剂,并测定了它们对两种保留型β-葡萄糖苷酶、一种β-半乳糖苷酶、一种β-木糖苷酶和几种纤维素酶的失活动力学参数。使用这类试剂进行荧光监测的活性位点滴定能够可靠地测量低至3 nM的活性酶浓度。
