在光系统 2 的析氧制剂中研究了 Mn 可逆萃取对由氧化的二次电子供体 (Z+) 产生的 ESR 信号 II 以及与还原的自旋耦合脱镁叶绿素 (pheo -) 和“初级”电子受体 (PA- -Fe (2+)) 相关的 ESR 双峰信号的影响。结果表明，Mn 萃取不会影响暗和光诱导 ESR 信号 II 和 ESR 双峰。结论是Mn不是光系统2二次电子给体Z的组成部分，其完全去除对Pheo(-)与PQ(-)-Fe(2+)配合物的交换相互作用没有影响。
The effect of reversible extraction of Mn on ESR signal II arising from the oxidized secondary electron donor (Z+) and the ESR doublet signal related to reduced spin-coupled pheophytin (pheo -) and "primary" electron acceptor (PA- -Fe (2+)) has been studied in oxygen evolving preparations of the photosystem 2. It is demonstrated that Mn extraction does not affect both dark and photoinduced ESR signal II and ESR doublet. A conclusion is made that Mn is not a component of the secondary electron donor Z of the Photosystem 2 and its complete removal has no effect on the exchange interaction of Pheo(-) and the PQ(-) -Fe(2+) complex.
