A multiwavelength transient-state kinetic study of the glutamate dehydrogenase catalyzed reaction has proven that an alpha-iminoglutarate complex is an observable intermediate in the reverse direction. It also shows the existence of two enzyme-NADPH-ketoglutarate complexes, only one of which reacts with ammonia rapidly.
对谷氨酸脱氢酶催化反应进行的多波长瞬态动力学研究已证明,α-亚氨基戊二酸复合物是逆向反应中可观测到的中间体。该研究还表明存在两种酶-NADPH-酮戊二酸复合物,其中只有一种能迅速与氨发生反应。
