酶是具有生物催化作用的蛋白质,生物体内一切新陈代谢过程几乎都是在酶的催化下进行。同工酶是酶的多分子形式,是一些来源相同、催化性质相同、而分子结构有差异的酶蛋白分子,它是基因表达的直接产物。植物的酯酶同工酶在不同作物、不同器官和不同生育时期有明显的差异。 Enzyme is a biocatalytic protein, all the metabolic processes in the organism are almost catalyzed by the enzyme. Isoenzymes are multimolecular forms of enzymes and are enzyme protein molecules with the same origin, catalytic properties, and molecular structure, which are the direct products of gene expression. Plant esterase isoenzyme in different crops, different organs and different growth stages have significant differences.
