摘要:
本文报道了音乐产生的振荡电场对自然环境中酵母液泡质子-ATP酶(V-ATP酶)活性的影响。振荡电场由浸入酵母空泡膜囊泡分散体中的电极产生,所述酵母空泡膜囊泡天然地容纳高浓度的活性V-ATP酶。在最刺激和最抑制的音乐下,V-ATP酶的ATP水解活性的显著差异是前所未有的。由于主题,即音乐对生物分子的影响,对于非科学的,深奥的神秘化是非常有吸引力的,我们为观察到的新现象提供了合理的解释。良好的相关性被发现之间的变化,在特定的酶的活性和组合强度的某些频带的傅立叶光谱的音乐剪辑。最突出的确定的频率是和谐的相互关系和估计的旋转速率的酶。这些结果导致的结论,振荡电场干扰周期性的跨膜电荷运动的工作酶。
英文摘要:
The effect of an oscillating electric field generated from music on yeast vacuolar proton-ATPase (V-ATPase) activity in its native environment is reported. An oscillating electric field is generated by electrodes that are immersed into a dispersion of yeast vacuolar membrane vesicles natively hosting a high concentration of active V-ATPase. The substantial difference in the ATP hydrolysing activity of V-ATPase under the most stimulating and inhibiting music is unprecedented. Since the topic, i.e. an effect of music on biomolecules, is very attractive for non-scientific, esoteric mystification, we provide a rational explanation for the observed new phenomenon. Good correlation is found between changes in the specific activity of the enzyme and the combined intensity of certain frequency bands of the Fourier spectra of the music clips. Most prominent identified frequencies are harmonically related to each other and to the estimated rotation rate of the enzyme. These results lead to the conclusion that the oscillating electric field interferes with periodic trans-membrane charge motions in the working enzyme.
