一、研究概况酶是催化各种生物化学反应的重要物质,种类多并各自有特殊的功能。一般说来,同功酶是指那些生物功能相同或接近相同,但其蛋白质性质及氨基酸组成不同的酶类,现已发现有一百多种。近二十多年来,同功酶的研究有了很大的进展,有些同功酶已用于临床诊断,从而为在分子水平上探讨疾病的本质及发病机理,以及对医学科学、肿瘤生化、遗传学等研究提供重要的手段。按照国际生化命名委员会的建议,同功酶的含义应该是在同一 First, the research overview Enzymes are catalyzed a variety of biochemical reactions of important material, variety and each have their own special functions. In general, isozymes are those that have the same or nearly identical biological function, but differ in their protein nature and amino acid composition, and more than one hundred have been found. In the recent two decades, great progress has been made in isozyme research. Some isozymes have been used in clinical diagnosis, so as to explore the nature and pathogenesis of the disease at the molecular level, as well as on the medical science, tumor biochemistry , Genetics and other research to provide an important means. According to the recommendations of the International Committee for Biochemical Nomenclature, the meaning of isozyme should be in the same
