The influence of Mn on saturation curves of ESR spectra of Ph(-) and P(+)(680) at 1-200K in samples with different content of Mn has been studied. An analysis of these data and those on photoinduced changes of fluorescence yield of chlorophyll leads to the conclusion that the Mn-containing centre in Photosystem 2 is a cluster of 4 Mn atoms, two of which can be replaced by Mg(2+) or any other divalent metal. The distances between Mn Na Ph as well as between Mn and P(680) have been estimated.
研究了不同锰含量样品中，锰对1-200K温度下Ph(-)和P(+)(680)的电子自旋共振光谱饱和曲线的影响。对这些数据以及叶绿素荧光产量光致变化的数据进行分析后得出结论：光系统2中含锰中心是由4个锰原子组成的簇，其中两个可被Mg(2+)或任何其他二价金属取代。已估算出锰与Ph以及锰与P(680)之间的距离。
