Mn-complexes in which Mn atom ligand with the N atom within ligand can stimulate the recovery of electron transfer and oxygen evolution. The trinuclear Mn-complex is extremely sensitive to the addition of CaCl2. It is suggested that there is an interaction between Ca2 and carboxyl within the trinuclear Mn-complex during photoactivation and this interaction benefits the ligation of Mn atom to the apo-WOC and form an active WOC. Binuclear MnMn complex shows slightly higher efficiency than binuclear MnMn complex in restoration of O2 evolution activity. It is suggested from our results that recovery of electron transport and O2 evolution with synthetic Mn-complexes is affected by different factors. Cl- can stimulate the reconstitution of WOC at the concentration of over 100mM;the maximal recovery of O2 evolution activity requires the presence of CaCl2 and 33 kDa protein polypeptide together. Bicarbonate can stimulate the reconstitution of WOC.

锰配合物中锰原子与配体中的氮原子配位连接时，能显著恢复电子传递活性和放氧活性；三核锰化合物在重组时对CaCl2的存在非常敏感，我们认为Ca2 与三核锰化合物中的羧基之间存在一定的相互作用，而这种作用有助于锰原子的光配位进而使三核锰化合物易于组装成有活性的水氧化复合物：双核锰化合物MnMn比双核锰化合物MnMn在恢复放氧活性方面更有效；影响锰化合物电子传递能力恢复的因素与影响锰化合物放氧活性恢复的因素不同；在锰蔟重组过程中，氯离子的浓度必须在100mM以上，才能有效进行光重组；最大光重组效率的获得必须有钙离子和33kDa多肽同时存在；碳酸氢根离子促进锰化合物与去锰光系统II的光组装。

Associated minerals are primary glauberite, halite and terrigenous mud; while calcite is absent or rare. The X-ray diffraction analysis shows that the mud-sized crystalline dolostone has an average CaCO3 mole content of 57.30% and an average degree of order of 0.40, revealing the characteristics of higher calcium content and lower degree of order. It is closely intergrown with glauberite, indicating that the aqueous medium in the depositional environment of mud-sized crystallinedolostone was hypersaline water or dilute brine. The temperature of water in the depositional environment calculated according to the oxygen isotope data averaged 30.5℃ and the minimum homogenization temperature of inclusions in primary glauberite crystals associated with mud-sized crystalline dolomite was 44℃. The two groups of temperature data are close, indicating that the temperature of the water in the paleolake environment during the deposition of mud-sized crystalline dolostone ranged from 30.5℃ to 44℃.
