摘要
提取冬小麦苗期叶绿体，研究了Ｌａ３＋离子作用下的Ｈｉｌｌ反应活性动力学性质结果表明：Ｌａ３＋离子对于Ｈｉｌｌ反应过程的两个关键部位具有明显的激活作用，这两个关键部位结合Ｌａ３＋离子的别构位点数目分别是５～６，９～１０个。这可能是Ｌａ３＋离子促进冬小麦光合作用机理的重要方面。
The effect of La3+ on Hill reaction of winter wheat chloroplast was studied. The result shows that the effect of La3+ on 2 sites. The allosteric sites in which La3+ is integrated with 2 key enzymes are 5-6 and 9 -10 respectively. The result is helpful to reveal the mechanism about La3+ promotes the photosynthesis.
