Abstract

Aortic intima N-acetyl-glucosaminyl-transferase has been purified by chromatography and isoelectric focusing, allowing her resolution into two insoenzymes, GN 1 (pHi = 4.2) and GN 2 (pHi = 8.5). The phenomenological analysis of this isoenzymes, involving two substrates and two products, showes one mechanism: Bi-Bi random.

摘要

主动脉内膜N-乙酰葡糖胺基转移酶已通过色谱法和等电聚焦法纯化，从而将其解析为两种同工酶，即GN 1（pHi = 4.2）和GN 2（pHi = 8.5）。对这种涉及两种底物和两种产物的同工酶的现象学分析显示出一种机制：双底物随机机制。
