Abstract

The deoxy form of hemocyanins and tyrosinases from certain species displays a weak low-energy luminescence when solutions of the protein are irradiated with light at approximately 290 nm. The emission most likely results from a copper-to-imidazole charge transfer state as shown by studies with a synthetic copper(I) complex having three imidazole ligands.

摘要

当用约290纳米的光照射某些物种的血蓝蛋白和酪氨酸酶的脱氧形式的蛋白质溶液时，它们会显示出微弱的低能量发光。如对具有三个咪唑配体的合成铜（I）配合物的研究所表明的，这种发射最有可能源于铜到咪唑的电荷转移态。
