Studies on Properties of Tyrosyl Residues in Photosystem ⅱ in the Presence of Anionic Surfactant

阴离子表面活性剂存在下光系统Ⅱ中 酪氨酸残基的性能研究

In addition the conformation and microenvironment of tyrosyl residue of proteins were markedly affected .

同时 酷 氨 酯残 基 中 酚 环 的 构象和微极性 发生了改变。

The results have shown that there exist excitation energy transfers from the component at 232 nm in PS ⅱ proteins to the tyrosyl residues and from these two amino acid residues to chlorophyll a.

在PSⅡ蛋白质 内部，存在着 232nm 处 的 组 分 与 酪氨酸 之间以及这两种氨基酸残基与叶绿素a之间的能量传递。

The results indicate that all three tyrosyl side chains of DPI are unmasked and situated on the surface of the molecule .

这些结果说明DPI的三个 酪氨酸侧链暴露在分子表面。
