• 介紹：

  自刀豆和豌豆等籽粒中提取而得的一種植物凝集素(1ectin)。為四聚體球蛋白，分子量102000。每個亞基含237個氨基酸殘基，分子量25500，結(jié)合一個Ca2+和一個Mn2+，含一個糖結(jié)合部位。能與α-甘露糖、α-葡萄糖(細(xì)胞膜糖蛋白上)專一地結(jié)合，結(jié)合位點要求是α-D-吡喃甘露糖或α-D吡喃葡萄糖六元環(huán)中的C-3/C-4和C-6未被取代羥基。能與以α-1，2糖苷鍵連接的甘露二糖和甘露三糖有最大的親和力。它為促細(xì)胞有絲分裂素(mito-gen)，主要對T淋巴細(xì)胞有激發(fā)作用，凝集紅細(xì)胞和動物精子，抑制腫瘤細(xì)胞運動，以及延長異源移植存活時間等作用。一種重要的生化和免疫研究試劑。
