| 摘 要： | 本文阐述了光对高等植物乙醇酸氧化酶活性的影响,分析了白光、光强度、光质等对酶的诱导作用,讨论了前人解释光的作用机制的几种学说,在此基础上提出了另一个光对乙醇酸氧化酶诱导机理的假说,认为光对该酶的诱导有两方面的作用,一是进行光合作用产生乙醇酸,乙醇酸诱导酶蛋白合成;二是光促进体内FMN的生物合成与还原。所合成的酶蛋白再与FMN结合成全酶而表现出催化活性。

| Abstract: | This paper gives a review about the effects of light on the activities of glyoclate oxidase in higher plants, It analyses the induction of glycolate oxidase by white light, light intensities, light qualities, etc., and discusses several hypotheses with which the former workers explained the action mechanism of light on this enzyme. On this basis, a new hypothesis is proposed, suggesting that the effect of light has two aspects. One of these is to make glycolic acid by setting photosyn-thetic process in motion. Then, being an effector, glycolic acid induces the biosynthesis of apoenzyme of glycolate oxidase. The other aspect of light effect is to acelerate the biosynthesis and changes of flavines and to raise the level of FMN in tissues. Then, FMN enters into combination with apoenzyme to make the holoenzyme of glycolate oxidase. |
