生物体内一切新陈代谢过程几乎都是在酶的催化下进行的。千差万别的酶分子各尽其责,有独自的催化功能(做不同的工作),如淀粉酶催化淀粉水解,蛋白酶促使肽键断裂。但人们还发现了另一些酶,它们在催化相同的反应(即做同样的工作),只是结构和理化性质或多或少的差异,导致在生物体内分布,调控及生理功能的差别,这就是同工酶。随着同工酶分析技术的突破,其在生命科学中的应用日益广阔。种子研究也是同工酶技术大显身手的领域。
Almost all metabolic processes in the body are catalyzed by enzymes. Different enzyme molecules do their duty, with its own catalytic function (do different work), such as amylase-catalyzed starch hydrolysis, protease to promote peptide bond cleavage. However, there are also other enzymes found that catalyze the same reaction (ie do the same work), but differ more or less in structure and physicochemical properties, resulting in differences in distribution, regulation and physiological functions in the organism, which is Isoenzyme. With the breakthrough of isoenzyme analysis technology, its application in life sciences has become increasingly broader. Seed research is also an area where isozyme technology works.
