Bovine milk galactosyltransferase was incorporated into vesicles prepared from different phosphatidylethanolamines which varied widely in both their gel-liquid crystalline and their lamellar-hexagonal phase transition temperatures. Although all phosphatidylethanolamines stimulated the activity of the enzyme the extent of stimulation varied. Acidic lipids phosphatidylserine and phosphatidic acid inhibited the activity of the enzyme incorporated into all of the phosphatidylethanolamines except when the enzyme was in soya PE in which the acidic lipids had no effect.
牛乳糖基转移酶被整合到由不同磷脂酰乙醇胺制备的囊泡中,这些磷脂酰乙醇胺在其凝胶 - 液晶态和层状 - 六方相转变温度方面差异很大。尽管所有磷脂酰乙醇胺都能刺激该酶的活性,但刺激程度各不相同。酸性脂质磷脂酰丝氨酸和磷脂酸会抑制整合到所有磷脂酰乙醇胺中的该酶的活性,不过当该酶存在于大豆磷脂酰乙醇胺中时,酸性脂质则没有影响。
