Modeling approaches have been used to develop insight into the nature of the redox activesite of the free-radical-containing copper metalloenzyme galactoseoxidase. The optical spectrum of the free radical generated by low-temperature UV irradiation of (methylthio)cresol is nearly identical to that observed for the free-radical site in metal-free apo galactoseoxidase, supporting the assignment of
建模方法已被用于深入了解含自由基的铜金属酶半乳糖氧化酶的氧化还原活性位点的性质。由(甲硫基)甲酚低温紫外线照射产生的自由基的光谱与在无金属载脂蛋白半乳糖氧化酶中观察到的自由基位点几乎相同,支持将蛋白质自由基分配给新型酪氨酸-半胱氨酸共价交联结构最近从 X 射线晶体学研究报告。这种新型生物氧化还原基团的化学基本表征包括测量对酚质子酸性的取代基效应和观察(甲硫基)甲酚与过氧化物的氧化作用
