The removal of the 43 kDa peptide from postsynaptic membranes from the electric organ of Torpedo by alkaline treatment (pH 11) or by lithium diiodosalicylate at pH 8 results in similar ultrastructural changes that cannot be produced by the action of porcine pancreatic phospholipase A2 or lysophosphatidylcholine. Thin-layer chromatography fails to reveal significant alkaline hydrolysis of membrane lipids from postsynaptic membranes and erythrocyte ghosts under the conditions used for peptide extraction.
用电鳐电器官的突触后膜进行碱性处理(pH 11)或在pH 8条件下用二碘水杨酸锂去除43 kDa肽,会导致类似的超微结构变化,而猪胰磷脂酶A2或溶血磷脂酰胆碱的作用无法产生这种变化。在用于肽提取的条件下,薄层色谱未能显示突触后膜和红细胞膜的膜脂有明显的碱性水解。
