They distinguish themselves from other plant proteins by the ability of carbohydrate binding. Most plant lectins are directed to bind foreign polysacchride. Plant lectin is believed to take part in the defense responses against invader. In this paper we presented a review on the classification, characters, functions, crystal structure and functions related to the carbohydrate binding activity. 植物凝集素 糖结合活性 晶体结构 功能 抗虫植物基因工程 plant lectin carbohydrate binding ability crystal structure functions insect-resitant plant genetic engineering Q946.1 2002-02-01 2021-04-01 2
