Abstract
Kinetic curves of paramagnetic centres accumulation and quenching of the luminescence of UV-irradiated proteins at 77 degrees K are compared. Initiation of luminescence of UV-irradiated proteins at the annealing of paramagnetic centres was studied. The luminescence of UV-irradiated proteins was shown to be quenched with the paramagnetic centres formed. It was shown that protein absorption spectrum was not changed when the limiting concentration of paramagnetic centres was obtained in it.
摘要
比较了顺磁中心积累的动力学曲线以及77K下紫外线照射蛋白质发光的猝灭情况。研究了顺磁中心退火时紫外线照射蛋白质发光的起始情况。结果表明，紫外线照射蛋白质的发光会被形成的顺磁中心猝灭。研究还表明，当蛋白质中顺磁中心达到极限浓度时，其吸收光谱并未改变。
