ELF e.m.金属蛋白氧化还原活性位点场
Effect of ELF e.m. fields on metalloprotein redox-active sites
摘要：
酶中金属离子的分布和几何形状的特殊性促使我们提出这样的假设：活性部位的金属离子就像微小的天线，能够接收非常微弱的电磁波。信号.研究了Cu ~（2+）、Zn ~（2+）超氧化物歧化酶（SOD_1）和Fe ~（2+）黄嘌呤氧化酶（XO）在体外产生和清除自由基后的酶活性。我们观察到，XO产生的超氧自由基增加了一个弱场具有拉莫尔频率fL的Fe 2+，而SOD 1动力学是明显减少暴露于一个弱场具有频率fL的Cu 2+离子。
英文摘要：
The peculiarity of the distribution and geometry of metallic ions in enzymes pushed us to set the hypothesis that metallic ions in active-site act like tiny antennas able to pick up very feeble e.m. signals. Enzymatic activity of Cu2+, Zn2+ Superoxide Dismutase (SOD1) and Fe2+ Xanthine Oxidase (XO) has been studied, following in vitro generation and removal of free radicals. We observed that Superoxide radicals generation by XO is increased by a weak field having the Larmor frequency fL of Fe2+ while the SOD1 kinetics is sensibly reduced by exposure to a weak field having the frequency fL of Cu2+ ion.
