测定了黑腹果蝇幼虫体内鸟氨酸脱羧酶（l-鸟氨酸羧化酶，EC 4.1.1.17）和s -腺苷-蛋氨酸脱羧酶（s -腺苷-l -蛋氨酸羧化酶，EC 4.1.1.50）的含量。24和48 h时酶活性最高，随后各龄期酶活性逐渐降低。腐胺对s -腺苷蛋氨酸脱羧酶的刺激作用在幼虫发育后期明显，但在早期不明显。
Ornithine decarboxylase (L-ornithine carboxy-lase, EC 4.1.1.17) and S-adenosyl-methionine decarboxylase (S-adenosyl-L-methionine carboxy-lase, EC 4.1.1.50) were assayed in Drosophilia melanogaster larvae. The highest enzyme activities were detected in 24 and 48 h larvae, with diminishing activities in subsequent larval stages. Stimulation of S-adenosylmethionine decarboxylase by putrescine was demonstrable in late but not in early stages of larval development.
