Dipeptidylaminopeptidase IV, a plasma membrane-bound glycoprotein, is characterized by an intramolecular heterogeneous turnover of the protein backbone and carbohydrate chain. The faster turnover of the latter is restricted only to the outer sugars. The inner core sugars D-mannose and N-acetyl-D-glucosamine turn over at the same rate as the protein backbone.
二肽基肽酶IV是一种结合于质膜的糖蛋白，其特点是蛋白质主链和糖链在分子内的周转存在异质性。后者较快的周转仅局限于外层糖。核心内层糖D-甘露糖和N-乙酰-D-葡萄糖胺的周转速率与蛋白质主链相同。
