磷酸烯醇式丙酮酸羧化酶的光调节

Light-Regulation of Phosphoenolpyruvate Carboxylase in Plants

就光对磷酸烯醇式丙酮酸羧化酶的光调节作用做一综述。

The effects of light on phosphoenolpyruvate carboxylase (PEPCase) inC. and CAM plants were reviewed. There were two effects for light on PEPCase,onewas activation of existed PEPCase by light, and the other was light-induced formationof PEPCase. Because light activation was rapid and accurate, and light-induced formation was slow, but had lasting effects,the former was also called fine-regulation,whereas the later was called crztde-regulation or long-term regulation.
