A study on the transfer of copper from Cu-thionein into apo-caeruloplasmin, using Cu-thionein that was previously oxidised by activated leucocytes, was performed. Cu(I)-thiolate oxidation was conveniently monitored by the progressive decline of the specific Cotton bands between 400 and 300 nm. The characteristic e.p.r. properties and NN-dimethyl-p-phenylenediamine oxidase activity indicated a successful formation of caeruloplasmin. Taking into account the simultaneous occurrence of leucocytes, apo-caeruloplasmin and Cu-thionein in blood plasma, such an interaction would favour a possible metabolic link between either copper protein.
利用先前被活化白细胞氧化的铜硫蛋白,开展了一项关于铜从铜硫蛋白向脱辅基血浆铜蓝蛋白转移的研究。通过400至300纳米之间特定科顿带的逐渐下降,可方便地监测硫醇铜(I)的氧化。特征性的电子顺磁共振特性和N,N-二甲基对苯二胺氧化酶活性表明成功形成了血浆铜蓝蛋白。考虑到白细胞、脱辅基血浆铜蓝蛋白和铜硫蛋白同时存在于血浆中,这种相互作用将有利于这两种铜蛋白之间可能存在的代谢联系。
