制备了碳酸酐酶II突变体His64Cys,并将其应用于系链炔/叠氮化物环加成反应。叠氮化物组分可以通过二硫桥连接到酶表面,而炔组分则通过磺胺锚点可逆地配位到酶原催化中心的锌离子上。用晶体学表征了反应物在结合位点的初始取向和形成的三唑产物。高效液相色谱-质谱分析可监测反应过程。
The carbonic anhydrase II mutant His64Cys was prepared and applied to tethered alkyne/azide cycloaddition reactions. The azide component could be tethered to the enzyme surface through a disulfide bridge, while the alkyne component was reversibly coordinated through a sulfonamide anchor to the zinc ion in the original catalytic center of the enzyme. The incipient orientation of the reactants in the binding site and of the formed triazole product were characterized by crystallography. The reaction progression could be monitored by HPLC‐MS analysis.
