摘　　要：凝集素是一类专一、可逆地和糖类结合的蛋白质，迄今已经分离纯化并测定了氨基酸序列的凝集素已有不少，一些凝集素以及它们与配体糖相互结合的复合物的高级结构也已经给出，许多工作已深入到基因水平．就目前已有的知识，说明植物凝集素是一个庞大的蛋白质家族．Lectins are a kind of carbohydrate-binding pro-teins. Though they differ in their carbohydratespecificities, they resemble each other in manyphysicochemical properties. By now, a lot ofplant lectins have been sequenced, and some oftheir three-dimensional structures have beenestablished. A few lectin genes have beencloned. Comparison of their primary sequencesand tertiary structures, we can find that plantlectins are several large groups of homologousproteins belonging to a superfamily.
