The activation effect of univalent ions (K+ and Na+) on GAT enzyme activity was stronger than that of divalent ions (Mg2+ and Mn2+), among which Na+ was the strongest and the GAT enzyme activity was obviously inhibited by Ca2+.

• 检测了6种金属离子对酶活性的影响,发现单价离子K+和Na+对GAT的激活作用高于双价离子Mg2+和Mn2+,其中Na+的激活作用最强,而Ca2+有明显的抑制作用。
