The amount of S-adenosyl-l-methionine decarboxylase present in rat liver was enhanced 17-fold by administration of methylglyoxal bis(guanylhydrazone),* a specific inhibitor of the enzyme. The enzyme was purified 1400-fold in 50% yield from such liver extracts by chromatography on columns of the inhibitor bound to Sepharose. The purified enzyme had no spermidine synthetase activity.
通过给予甲基乙二醛双(脒腙)(该酶的一种特异性抑制剂),大鼠肝脏中S-腺苷-L-甲硫氨酸脱羧酶的含量增加了17倍。通过在与琼脂糖结合的抑制剂柱上进行层析,从这种肝脏提取物中以50%的产率将该酶纯化了1400倍。纯化后的酶没有亚精胺合成酶活性。
