Abstract
Ferredoxin-dependent glutamate synthase has been found in cells of thermophylic Chlorella strain Ch. pyrenoidosa 82T. The enzyme is active with its own ferredoxin and that of Spirulina. Glutamate synthase activity increases during nitrogen starvation and than decreases in the course of successive ammonium assimilation. The scheme of ammonium assimilation in Chlorella pyrenoidosa 82T cells is proposed.
摘要
在嗜热小球藻菌株Ch. pyrenoidosa 82T的细胞中发现了依赖铁氧化还原蛋白的谷氨酸合酶。该酶对自身的铁氧化还原蛋白以及螺旋藻的铁氧化还原蛋白都有活性。在氮饥饿期间，谷氨酸合酶活性增加，随后在连续的铵同化过程中降低。提出了小球藻Ch. pyrenoidosa 82T细胞中铵同化的方案。
