Relationship of glutamate dehydrogenase levels to free amino acids, amides and ammonia in excised oat leaves

概要

論文の詳細を見る
Levels of glutamate dehydrogenase (GDH) increase 12 fold in detached oat leaves during 96 hr incubation with 15 mM ammonia. The slight elevation of GDH detected within the first 24 hr was followed by increasing rates of enzyme production in subsequent periods. Rapid increases in free ammonia and amino acids with a marked synthesis of glutamine and decreases of glutamate and aspartate were observed during the initial stages of ammonium assimilation.
