A comparative study was performed for rabbit muscle phosphofructokinase (PFK) from normal and atherosclerotic animals. The diagonal electrophoretic technique was used for cysteic acid containing peptides separation. On performic acid oxidation among the tryptic peptides of PFK the disulphide containing peptide was found. Its electrophoretic mobility, compared to that of cysteic acid, gives ground for intrasubunit disulphied bond existence.
对来自正常动物和动脉粥样硬化动物的兔肌肉磷酸果糖激酶（PFK）进行了一项比较研究。采用对角线电泳技术分离含半胱磺酸的肽段。在PFK的胰蛋白酶肽段经过甲酸氧化后，发现了含二硫键的肽段。与半胱磺酸相比，其电泳迁移率为亚基内二硫键的存在提供了依据。
