Lectins are a class of proteins with specific and reversible carbohydrate binding properties. Plant lectins constitute the group of these proteins most studied, placing emphasis on the legume family. The Caesalpinioideae subfamily is part of Leguminosae and second only to Papilionoideae with more published works on lectins. Classically, Caesalpinioideae is formed by 171 genera and 2250 species. It presents 13 genera with reports of lectins, featuring the Bauhinia genus with the greatest number of species having purified and characterized lectins. Comparing genera, the lectins in this subfamily do not have similar physicochemical or structural properties. Collectively, however, antibacterial, antiviral, and anticancer activities have been reported, as well as applications as biosensors and biomarkers. This review aims to summarize the available data on purified lectins from species of the Caesalpinioideae subfamily, demonstrating the characteristics of these molecules and the potential for their application in future studies of new lectins, as well as of application in several areas.

凝集素是一类具有特异性和可逆碳水化合物结合特性的蛋白质。植物凝集素构成最受研究的这些蛋白质的组，着重于豆科植物。该云实亚科亚科是部分豆科与仅次于蝶形花亚科与凝集素更发表作品。传统上，Ca属由171属和2250种组成。它以紫荆花为特色，介绍了13个属的凝集素报告具有纯化和鉴定的凝集素种类最多的菌属。相比之下，该亚科中的凝集素没有相似的物理化学或结构特性。然而，集体地已经报道了抗菌，抗病毒和抗癌活性，以及​​作为生物传感器和生物标志物的应用。这篇综述的目的是总结有关凯氏pin亚科物种纯化的凝集素的可用数据，证明这些分子的特性以及它们在新凝集素的未来研究中的应用潜力以及在某些领域的应用。
