摘要

本论文研究了光合作用暗反应中的二个关键酶：ＲｕＢＰＣａｓｅ－ＯＸａｓｅ和ＰＥＰＣａｓｅ．稀土使这两个酶羧化活性提高．稀土使ＲｕＢＰＣａｓｅ活性增加由两方面原因造成：１、稀土使ＲｕＢＰＣａｓｅ本身活性增加，２、稀土使ＲｕＢＰＣａｓｅ含量增加．稀土对ＲｕＢＰＯＸａｓｅ的加氧活性影响不大．因此对光呼吸影响不大．稀土使ＲｕＢＰＣａｓｅ－ＯＸａｓｅ的Ｃａｓｅ／ＯＸａｓｅ比值增加，有利于反应向羧化方向进行

Abstract

This thesis deals with two key enzymes RuBPCase OXase and PEPCase which take part in the dark reaction of photosynthesis.Rare earth improves the activation of case of the two enzymes

fixes more CO 2

strengthens photosynthesis metabolism and thus

more organic compound are produced. The improvement of the activity of RuBPCase by rare earth is caused by two reasons:1)Rare earth can strengthen the activation of PuBPCase itself.2) It can also increase RuBPCase content. Rare earth has little influence on oxygenation of RuBPCase

so it has little influence on photorespiration either. Rare earth can increase the case/oxase ratio of RuBPCase OXase and this helps the reaction develop towards case. Acceleration of Ce to the activation of case of RuBPCase and PEPCase is greater than that of Ce.
