Abstract

A rhamnose-specific lectin was isolated from ovaries of the grass carp (Ctenopharyngodon idellus). The grass carp lectin possesses a molecular mass of 205 kDa. It is composed of six subunits each with a molecular mass of 35 kDa. The N-terminal amino acid sequence of the grass carp shows similarity to those of other fish species with 26-35% amino acid identity. It is mitogenic toward murine splenocytes and peritoneal exudate cells.

摘要

从草鱼(Ctenopharyngodon idellus)的卵巢中分离出一种鼠李糖特异性凝集素。草鱼凝集素的分子量为205 kDa。它由六个亚基组成,每个亚基的分子量为35 kDa。草鱼的N端氨基酸序列与其他鱼类的序列相似,氨基酸同一性为26%-35%。它对小鼠脾细胞和腹腔渗出细胞具有促有丝分裂作用。
