Abstract

Chloroplasts contain the enzyme glutamine synthetase. Formation of glutamine by isolated chloroplasts is light-dependent and requires an intact outer envelope. Addition of exogenous glutamic acid, as well as nitrogen donors such as nitrite or ammonium, stimulate the synthesis of this amide. Photosynthetic generation of ATP satisfies the light requirement of glutamine synthesis. The process is supported by cyclic as well as noncyclic photophosphorylation.

摘要

叶绿体含有谷氨酰胺合成酶。离体叶绿体合成谷氨酰胺依赖于光，需要完整的外被。添加外源性谷氨酸以及诸如亚硝酸盐或铵盐等氮供体可刺激该酰胺的合成。光合作用生成的 ATP 满足谷氨酰胺合成的光需求。该过程由环式和非环式光合磷酸化来支持。
