6-磷酸葡萄糖3-脱氢酶(NtdC)是在枯草芽孢杆菌NTD操纵子中编码的NAD依赖性氧化还原酶。NtdC氧化6-磷酸葡萄糖是kanosamine生物合成的第一步。该产品3-氧-d-葡萄糖6-磷酸酯(3oG6P)从未合成或分离过。在低pH和中性pH下,NtdC催化的反应非常缓慢,并且在pH 9.5附近其速率增加到最大值。然而,在碱性条件下,由于开环后使1,3-二羰基化合物去质子化,产物不稳定。由于该烯醇化物在310 nm处的吸收带与另一种酶促产物NADH的吸收带重叠,使动力学测量复杂化。我们报告了反应所得光谱的去卷积,以确定速率常数和可能的动力学机理。这样,我们能够确定3oG6P(23000 M –1 cm –1)烯醇的消光系数,从而可以测量一阶速率常数(5.51×10–3 s –1)和非酶性烯醇化物形成的活化能(93 kJ mol –1)。使用氘标记的底物,我们显示从碳3转移氢化物在酶促反
