同工酶分析可以作为遗传育种的生化指标,在当前农业育种现代化研究中是应予以重视和推广的技术。同工酶即Isozyme或Isoenzyme。我们知道酶是蛋白质;酶即生物体中各种生化反应的催化剂。没有酶,在常温常压的生物体内生化反应就不能进行。不同的生化反应是由不同的具有特异催化作用的酶进行催化的。而同一生化反应又往往有一个以上具有相同特异催化的酶参与。例如从化合物A变成化合物B的过程中如果发现有三个酶(E_1E_2E_3)都能进行催化,说明这三个酶有同样特异的催化A→B的作用,这种可以进行同样的工作,但是分子结构并不相同的酶就叫做同工酶,由于它们的结构不同,在
Isoenzyme analysis can be used as the biochemical index of genetic breeding, which should be emphasized and popularized in the current agricultural breeding modernization research. Isozymes Isozyme or isozyme. We know that enzymes are proteins; enzymes are the catalysts of various biochemical reactions in organisms. Without enzyme, biochemical reactions can not be carried out in the living body at normal temperature and pressure. Different biochemical reactions are catalyzed by different enzymes with specific catalytic activities. The same biochemical reactions often have more than one enzyme with the same specific catalytic participation. For example, from compound A to compound B, if three enzymes (E 1 E 2 E 3) were found to be catalyzed, it was shown that these three enzymes had the same specific effect of catalyzing A → B, and this could be done in the same way. However, Different structure of the enzyme is called the isozyme, due to their different structures
