本文研究了漆树漆酶Ⅰ型和Ⅱ型铜和猪铜蓝蛋白Ⅱ型铜的电子自旋回波衰减包络。核调制模式表明，咪唑是所有这些的配体。本文研究了漆酶中Ⅰ型铜离子的线性电场效应。该站点的对称性是近四面体和LEFE的大小与蓝色的强度相关。
Electron spin-echo decay envelopes for types I and II copper of Rhus vernicifera laccase and for type II copper of procine ceruloplasmin have been studied. Nuclear modulation patterns show that imidazole is a ligand for all of them. The linear electric field effect (LEFE) in EPR was studied for type I copper in a laccase preparation from which type II had been removed. The symmetry of the site is near tetrahedral and the magnitude of the LEFE is correlated with the intensity of blue color.
