Development of a highly sensitive Prussian-blue-based enzymatic biosensor for L-carnitine employing the thiol/disulfide exchange reaction.
本文首次报道了基于硫醇/二硫键交换反应的安培法乙酰转移酶L-肉碱传感器概念验证。肉碱乙酰转移酶(CrAT)催化乙酰辅酶A(acetyl-CoA)与L-肉碱反应,生成辅酶A(CoA)和乙酰L-肉碱。由于CoA分子较大且带负电,空间位阻和静电作用使其难以被电化学方法直接检测。该传感器在酶促反应中引入胱胺(cystamine),使CoA通...
