图1. 叶绿体Trx系统及其作用
叶绿体Trx系统在卡尔文循环中关键酶类、质体生物发生、硫代谢、胁迫应激及叶绿素、四吡咯和淀粉合成中发挥重要调节作用。FTR对5种Trx蛋白都有作用, 故图中未标出。SOQ1对PSII的亚基作用靶点未知。
Figure 1. Chloroplast Trx systems and their functions
The Trx systems in chloroplast play important roles in regulating key enzymes of Calvin cycle, plastid biogenesis, sulfur metabolism, stress response, and the synthesis of chlorophyll, tetrapyrrole, and starch. Since FTR affects all 5 Trx proteins, the lines are not marked in the figure. The target of SOQ1 on the PSII subunits is still unknown.
