Liposomes made of sphingomyelin were found to inhibit both ATP-activated and non-activated AMP deaminase from pig brain, in contrast to liposomes made of egg yolk phosphatidylcholine which exhibited an activating effect on the ATP-activated enzyme, being without effect on AMP deaminase in the absence of ATP. Dioleoylphosphatidylcholine exerted a similar effect as egg yolk phosphatidylcholine but dipalmitoylphosphatidylcholine was without effect.
结果发现,由鞘磷脂制成的脂质体能够抑制来自猪脑的ATP激活型和非激活型AMP脱氨酶,而由蛋黄磷脂酰胆碱制成的脂质体对ATP激活型酶具有激活作用,在无ATP的情况下对AMP脱氨酶无作用。二油酰磷脂酰胆碱发挥了与蛋黄磷脂酰胆碱类似的作用,但二棕榈酰磷脂酰胆碱则无作用。
